2-Way vs 3-Way Motorized Valves: Which One Does Your System Actually Need?

Reading Time: 15 minutes

Choosing between a 2-way and 3-way motorized valve can make or break your system’s efficiency. A 2-way valve with two ports controls fluid flow in one direction—perfect for simple on/off applications like irrigation zones or basic HVAC control. A 3-way valve with three ports handles more complex tasks by mixing or diverting fluids, making it essential for temperature regulation and chemical processing. While 2-way valves are simpler and more affordable, 3-way valves deliver the flexibility needed for dynamic systems. This guide breaks down everything you need to know to make the right choice for your application.

Picture this: You’re halfway through installing a new sprayer system when you realize the valve you ordered can’t handle the temperature mixing your application requires. Now you’re facing downtime, rushed shipping costs, and a frustrated customer. We see this scenario play out more often than you’d think—and it’s almost always because someone chose a 2-way valve when they really needed a 3-way, or vice versa.

The good news? Once you understand how these valves actually work and where each one excels, the choice becomes straightforward. Let’s break down everything you need to know to select the right valve the first time.

Frequently Asked Questions

1. What is a 2-Way Motorized Valve?

A 2-way motorized valve is your workhorse for straightforward flow control. With one inlet and one outlet, it operates like a simple on/off switch for liquids or gases. When you need to start or stop fluid flow without any fancy mixing or diverting, this is your valve.

Key Specifications:

Port Configuration: 1 inlet, 1 outlet
Typical Port Sizes: 1/4″ to 4″ (larger sizes available on request)
Pressure Ratings: 50-300 PSI depending on construction
Response Time: 2-30 seconds (varies by actuator and valve size)
Common Materials: Brass, stainless steel 316, glass-filled nylon
Voltage Options: 12V DC, 24V AC/DC, 120V AC, 240V AC
Service Life: 50,000-100,000+ cycles

Thanks to their electric actuators, these valves respond quickly and integrate seamlessly into automated systems. You’ll find them in everything from home irrigation controllers to industrial cooling systems. Their simple design means fewer parts to fail, which translates to rock-solid reliability when you need it most.

At Texas Industrial Remcor, we manufacture 2-way motorized valves specifically engineered for agricultural applications where dust, chemicals, and temperature extremes are daily realities. Our most popular model features corrosion-resistant construction and a manual override—because when you’re in the middle of spray season, you can’t afford to wait for an electrician.

2. What is a 3-Way Valve?

A 3-way valve takes fluid control to the next level with three ports that can mix or divert flows between multiple paths. Think of it as a traffic controller that can either blend two incoming streams or redirect one stream to different destinations.

Key Specifications:

Port Configuration: 2 inlets + 1 outlet OR 1 inlet + 2 outlets
Typical Port Sizes: 1/2″ to 4″ (custom sizes available)
Pressure Ratings: 50-300 PSI (application-dependent)
Response Time: 5-60 seconds for full stroke
Common Materials: Brass, stainless steel 304/316, PTFE seals
Voltage Options: 24V AC/DC, 120V AC, 240V AC
Modulating Range: 0-100% adjustable flow
Service Life: 30,000-60,000 cycles (higher maintenance)

This versatility makes 3-way valves essential when you need precise control over mixing ratios or when one fluid source needs to serve multiple destinations. For example, in an agricultural spray system with both herbicide and water tanks, a 3-way mixing valve ensures you maintain exactly the concentration you need—whether that’s 5% or 15%—automatically adjusting as flow rates change.

The tradeoff? More complexity means a higher price tag and slightly more maintenance. But when your application demands this level of control, there’s simply no substitute.

3. How Does a 2-Way Valve Function?

The operation of a 2-way valve is elegantly simple: it’s either fully open or fully closed. When open, fluid flows directly from inlet to outlet with minimal restriction. When closed, the valve creates a complete seal that stops all flow.

Operating Mechanism:

Normally Closed (NC): Remains shut until powered; opens when energized
Normally Open (NO): Stays open until powered; closes when energized
Power Failure Mode: Returns to “normal” position (critical for safety planning)

The electric actuator typically uses a simple solenoid or small motor to move the valve element. In automated systems, you can add position switches or feedback sensors for monitoring, though many applications work perfectly fine with basic open/closed control.

Here’s what makes these valves so reliable: flow always moves in one fixed direction, which means no confusion about plumbing orientation. This simplicity also keeps energy consumption low—most models draw 5-20 watts during operation, and some newer designs only consume power during the switching action.

Real-World Example: On a center pivot irrigation system, 2-way valves control individual spray zones. When the controller signals zone 3 to activate, the valve opens in under 3 seconds, water flows through that zone, and when it’s time to move on, the valve snaps shut. Simple, reliable, and it happens thousands of times per season without maintenance.

4. How Does a 3-Way Valve Function?

A 3-way valve operates in two primary modes—mixing or diverting—depending on how you configure the ports:

Mixing Mode (2 inlets → 1 outlet): The valve combines fluids from two different sources into a single output stream. The actuator precisely controls how much flow comes from each inlet, letting you dial in exact mixing ratios.

Diverting Mode (1 inlet → 2 outlets): The valve takes flow from one source and directs it to either of two destinations, or proportionally splits it between both outlets.

Operating Mechanism: Unlike the simple on/off motion of a 2-way valve, a 3-way valve uses a more sophisticated actuator that can position itself anywhere from 0% to 100%. This modulating capability allows for continuous adjustment rather than just open/closed states.

Many 3-way valves include feedback sensors that report the current valve position to your control system. This real-time monitoring ensures you’re getting exactly the mixing ratio or flow split you programmed. The tradeoff is higher power consumption—typically 15-30 watts—and the need for occasional calibration to maintain accuracy.

Real-World Example: In a heated livestock watering system, a 3-way mixing valve blends hot water from a boiler with cold water from the main line. When outside temperatures drop, the valve automatically increases the hot water ratio to maintain 55°F at the drinking trough. If the control sensor detects 58°F water, the valve immediately adjusts to add more cold water—all without any human intervention.

At Texas Industrial Remcor, we’ve designed 3-way valves for specialty agricultural applications like automated fertilizer injection systems, where precise mixing ratios directly impact crop yields. Our valves include built-in bypass ports for emergency manual operation—because nitrogen application can’t wait for a service call.

5. Common Applications for 2-Way Valves

2-way motorized valves excel in any application where you simply need to turn flow on or off. Here’s where you’ll typically see them in action:

Agricultural & Irrigation:

Zone control in drip irrigation systems
Individual spray boom section control
Livestock watering system shutoffs
Automated pond filling operations

HVAC & Climate Control:

Chilled water line control in commercial buildings
Hot water baseboard heat zone valves
Rooftop unit makeup air control
Process air handling unit shutoffs

Industrial & Manufacturing:

Emergency coolant shutoff valves in CNC machines
Process water control in food processing lines
Pneumatic system air line control
Wash-down station activation valves

Safety & Protection:

Fire suppression system activation valves
Emergency chemical process shutdowns
Automated flood prevention systems
Boiler low-water cutoff protection

Municipal & Commercial Plumbing:

Building water service main control
Fountain and decorative water feature control
Pressure washer system activation
Automated restroom fixture control

We regularly supply 2-way valves to sprayer manufacturers who need reliable boom section control. A typical 60-foot boom might have six sections, each controlled by its own 2-way valve. The operator can turn individual sections off when approaching obstacles or when spray overlap would waste product—potentially saving hundreds of dollars per tank on expensive crop protection chemicals.

6. Common Applications for 3-Way Valves

3-way valves are your go-to solution when you need to mix, blend, or divert flows. These applications require the flexibility that only a three-port design can provide:

Temperature Control Systems:

Hydronic heating systems mixing supply and return water
Industrial process temperature regulation (maintaining 160°F ±2° in a pasteurization line)
Greenhouse floor heating with variable outdoor compensation
Engine cooling systems with thermostat bypass

Chemical Processing & Mixing:

Automated fertilizer injection in greenhouse operations (blending concentrated nitrogen with irrigation water at precise N-P-K ratios)
pH adjustment systems in water treatment plants
Herbicide mixing stations where concentrate mixes with carrier water
Industrial coating systems requiring exact viscosity control

Hydraulic System Control:

Mobile equipment with multiple hydraulic circuits
Priority valve systems directing flow to critical functions first
Pressure relief and bypass circuits
Load-sensing hydraulic systems

Multi-Source Distribution:

Dual boiler systems with automatic switchover
Well water/municipal water blending for agricultural operations
Backup generator coolant systems
Multiple tank source selection in spray applications

Advanced HVAC Applications:

Variable air volume (VAV) box control
Energy recovery ventilator mixing dampers
Chiller/boiler changeover valves in shoulder seasons
Geothermal loop temperature blending

Real Success Story: We recently worked with a large-scale vegetable operation in the Texas Panhandle that needed precise fertilizer injection across 400 acres. They were mixing liquid nitrogen from a bulk tank with well water, but seasonal variations in water pressure kept throwing off their injection rates—sometimes over-applying by 30%, other times under-applying and sacrificing yield.

Our solution used 3-way mixing valves with flow sensors at each field section. The system now automatically adjusts the mixing ratio based on real-time flow data, maintaining their target 28-0-0 concentration regardless of pressure fluctuations. The result? Their fertilizer costs dropped 18% in the first season while yields actually improved by 7% thanks to more consistent nutrition.

7. Flow Control Mechanisms of 2-Way Valves

The beauty of a 2-way valve is in its simplicity. Here’s what makes these valves so reliable:

Binary Operation: With only two states—fully open or fully closed—there’s no ambiguity about valve position. Your system either has flow or it doesn’t. This makes troubleshooting straightforward and eliminates the “is it partially open?” questions that can plague more complex valves.

Simple Actuation: Most 2-way valves use direct-acting solenoids for smaller sizes (under 1″) or spring-return actuators for larger valves. The mechanism is simple: energize to open (or close), de-energize to return to normal position. No complicated positioning logic required.

Pressure Compensation: While pressure differentials do affect flow rates, most 2-way valves can handle significant pressure variations without issue. A properly sized valve will deliver consistent performance across a 50-200 PSI range—covering most agricultural and light industrial applications.

Fast Response: Without the need to modulate position, 2-way valves switch states quickly. Small solenoid valves (1/2″ to 3/4″) typically open in 2-5 seconds. Even larger motorized ball valves (2″ to 4″) usually complete their stroke in 15-30 seconds.

Minimal Moving Parts: Fewer components mean fewer failure points. A typical 2-way valve has one seal, one moving element, and one actuator. Compare that to a 3-way valve with multiple seals and a complex actuator, and you’ll understand why maintenance intervals are longer and reliability is higher.

Dirt Tolerance: 2-way valves handle debris in the fluid stream better than 3-way valves. The straight-through flow path when open means particles are less likely to get trapped or interfere with sealing surfaces.

Low Maintenance Requirements: In agricultural applications, we see properly installed 2-way valves run 5-10 seasons before needing any service beyond occasional visual inspection. The most common “failure” is actually just a dirty coil or coroded wire connection—not the valve itself.

8. Flow Control Mechanisms of 3-Way Valves

3-way valves operate with considerably more sophistication, which brings both advantages and considerations:

Modulating Control: Unlike the binary operation of 2-way valves, 3-way valves can position themselves anywhere along a 0-100% range. This allows for infinite adjustment of mixing ratios or flow distribution. A well-designed control system can maintain mixing accuracy within ±2% across varying flow conditions.

Multi-Path Flow Management: The valve’s internal design creates multiple flow paths that can operate simultaneously. In a mixing application, for example, both inlet ports may be partially open at the same time, with their relative positions determining the final mixture ratio.

Complex Actuation: 3-way valves typically use electric actuators with gear reduction for precise positioning. Better models include internal potentiometers that feed back actual valve position to the controller—essential when accuracy matters. The actuator needs enough torque to overcome fluid pressure on both inlets, which is why they consume more power and cost more than 2-way actuators.

Feedback and Monitoring: Professional-grade 3-way valves often include position indication (either visual scales or electronic feedback) and end-of-stroke limit switches. This real-time monitoring lets your control system know exactly where the valve is and adjust accordingly.

Pressure Sensitivity: Because 3-way valves are managing flow from two sources or to two destinations, pressure imbalances can affect their performance. A 20 PSI difference between inlets, for instance, might shift your mixing ratio from 50/50 to 60/40 if the valve isn’t designed to compensate. Higher-quality valves include pressure-independent characteristics that maintain accurate control even with unbalanced systems.

Maintenance Considerations: The additional complexity means more parts that need occasional attention. Actuator calibration should be checked annually in critical applications. Seals on both inlet ports need periodic inspection. And the more sophisticated electronics may require professional service if problems develop.

Power Requirements: Modulating actuators need continuous power to hold their position in most designs (spring-return models are available but cost more). Count on 15-30 watts during operation—not much, but worth considering if you’re running dozens of valves on solar power.

When Precision Matters: Despite the added complexity, 3-way valves deliver control that simply isn’t possible with 2-way valves. At Texas Industrial Remcor, we’ve supplied 3-way valves for greenhouses where precise temperature control means the difference between thriving orchids and thousands of dollars in lost inventory. In those applications, the extra maintenance and cost are insignificant compared to the value of reliable performance.

10. How to Choose the Right Valve for Your Application

Here’s a straightforward decision framework based on decades of working with growers and equipment manufacturers:

Choose a 2-Way Valve When:

You only need to start or stop flow (boom section control, zone irrigation)
One fluid source serves one destination
Binary control is sufficient for your needs
Budget is a primary concern
Maintenance access is limited (pivot systems, remote installations)
Quick response is critical (emergency shutoffs)
You’re operating in harsh environments with debris-laden fluids

Choose a 3-Way Valve When:

You need to mix two fluid sources at variable ratios (hot/cold water blending, fertilizer injection)
One source must serve multiple destinations selectively (dual-circuit hydraulics)
Temperature control within tight tolerances is required
Flow distribution needs dynamic adjustment based on conditions
Your process benefits from modulating control rather than on/off operation
You have the budget and maintenance capability for more sophisticated equipment

Still Not Sure? Ask yourself these questions:

Am I combining fluids from two sources? → 3-way valve
Do I need temperature control? → 3-way valve
Am I just turning flow on and off? → 2-way valve
Is my budget under $200 per valve? → Probably 2-way valve
Can I access the valve easily for maintenance? → If no, favor 2-way valve

Frequently Asked Questions

What happens if I install a 2-way valve where I really need a 3-way valve?

You’ll lose the ability to mix or divert flows, which means your system can’t perform its intended function. For example, if you’re trying to blend hot and cold water for temperature control, a 2-way valve can only turn the hot water on or off—you can’t modulate the mixing ratio. You’d need to install two separate 2-way valves with complex control logic to approximate what one 3-way valve does simply and reliably.

Can I use a 3-way valve as a 2-way valve by capping one port?

Technically yes, but it’s wasteful. You’re paying for functionality you won’t use, and you’re introducing unnecessary complexity and maintenance. 3-way valves cost 3-4x more than equivalent 2-way valves and require more maintenance. If you only need on/off control, use a 2-way valve and save yourself money and headaches.

How do I size a valve for my application?

Start with your maximum flow rate in GPM (gallons per minute) and your system pressure. Look for a valve with a Cv (flow coefficient) rating that will deliver your required flow at your operating pressure differential. As a general rule: undersizing creates excessive pressure drop and flow restriction, while oversizing wastes money without improving performance. When in doubt, contact us—we’ll help you calculate the right size for free.

What’s the real-world lifespan I can expect from these valves in agricultural applications?

In typical agricultural use with seasonal operation and proper maintenance, expect 10-15 years from quality 2-way valves and 8-12 years from 3-way valves. The key is proper filtration (keep debris out), correct sizing (don’t exceed pressure ratings), and basic preventive maintenance (annual inspection, occasional actuator lubrication). We have customers running our valves for 20+ years in sprayer applications.

Do motorized valves work with my existing controller?

Most motorized valves are compatible with standard irrigation or process controllers. 2-way valves typically just need an on/off signal (closing a relay). 3-way modulating valves need either a 0-10V control signal or a 4-20mA current loop, which most modern controllers provide. Check your controller specs or give us a call—we can often suggest simple adapters if direct compatibility is an issue.

What maintenance do these valves actually need?

For 2-way valves: annual visual inspection, check for leaks, verify electrical connections are tight and corrosion-free. Every 5 years, consider replacing seals if you’re seeing any weeping. For 3-way valves: same annual inspection plus actuator calibration check, verify feedback sensors are accurate, lubricate actuator bearings per manufacturer specs (usually annually). Budget 30 minutes per valve for annual maintenance.

Can I use these valves with fertilizers, herbicides, or other agricultural chemicals?

Yes, but material compatibility matters. Brass and stainless steel valves handle most common agricultural chemicals, but some specialty herbicides or high-concentration fertilizers may require specific seal materials. Always check chemical compatibility for your specific products—we provide detailed compatibility charts with our valves and can recommend the right seal material (Viton, EPDM, PTFE) for your chemicals.

What voltage options are available, and does it matter which I choose?

Common options include 12V DC (battery/solar systems), 24V AC/DC (most agricultural controllers), 120V AC (standard US power), and 240V AC (high-power applications). Choose based on what your power supply and controller provide. Lower voltage systems (12V/24V) are safer for field installations and easier to troubleshoot, while 120V/240V options work well for stationary installations with grid power access.

What Is a Control Valve Diagram?

A control valve diagram is a schematic drawing that uses standardized symbols to represent a control valve and its related components. It illustrates the valve’s function, how it’s actuated, and its place within a larger process. These diagrams are a universal language for professionals in many industries.

The primary purpose of the diagram is to communicate design and operational information clearly and concisely. It is a key part of a larger piping and instrumentation diagram (P&ID), which maps out an entire process system. The P&ID includes all piping, instruments, and equipment, with the control valve diagram providing the specific details for each valve.

Engineers and technicians rely on these schematics for system design, installation, and daily operations. A properly drawn instrumentation diagram provides all the necessary information for troubleshooting and maintaining the system effectively. This includes details about the valve’s failure mode, connections, and control method.

Key Components of a Control Valve Diagram

To properly interpret a control valve diagram, you must first recognize the individual symbols. Each symbol represents a physical component of the valve assembly. Here are the core elements you will find on most diagrams.

1. Valve Body

The valve body is the main housing that contains the internal parts of the valve and through which the fluid flow is managed. Its symbol often indicates the type of valve being used. For instance, a globe valve, ball valve, or butterfly valve will each have a distinct symbol representing its body style.

The selection of the valve body type, such as a plug valve or diaphragm valve, depends on the application’s requirements. These requirements include the fluid type, pressure, temperature, and desired flow characteristics. The diagram shows how the valve connects to the larger piping system.

2. Actuator

The actuator provides the force needed to open or close the valve. It is mounted on top of the valve body and translates a control signal into physical motion. The diagram symbol will specify the type of actuator used, such as pneumatic, electric, or hydraulic.

Pneumatic actuators are common and are often shown with air supply lines. The symbol might also indicate if the actuator is single acting (spring-return) or double acting (air-powered in both directions). This detail is important for understanding the valve’s fail-safe position.

3. Valve Plug and Seat

Inside the valve body, the valve plug and seat are the components that directly control the fluid. The actuator moves the valve plug relative to the seat to increase or decrease the flow area. While these are internal components, their presence is implied by the function of the control valve symbol.

The interaction between these parts dictates the flow characteristics of the valve. The diagram as a part of the larger system documentation will correspond to a data sheet specifying the trim material and design. This ensures the valve performs as expected under operating conditions.

4. Positioner

A positioner is a device that improves the accuracy and responsiveness of the control valve. It compares the control signal from the system with the actual position of the valve stem and makes fine adjustments to the actuator. In a diagram, a positioner is typically shown as a small box mounted on the actuator.

Signal lines connect the positioner to the control system and to the actuator. This device is critical in applications requiring precise control over the fluid flow. Its inclusion in the diagram highlights the valve’s role in a feedback control loop.

5. Signal Lines

Signal lines on a control valve diagram indicate the type of communication and power used. Different line styles represent different types of signals, such as electrical, pneumatic, or data communication. For example, a dashed line often represents a pneumatic signal, while a solid line with hash marks might indicate an electrical signal.

Types of Control Valve Diagrams

Control valve diagrams come in several formats, each designed for a specific purpose. Understanding the differences helps you extract the right information. The level of detail varies depending on the diagram’s intended audience and use.

1. Cutaway Diagrams

Cutaway diagrams offer a detailed, cross-sectional view of the valve’s internal construction. They are primarily used for training and maintenance manuals. These drawings show how all the internal parts, like the valve plug and stem, fit together and function.

2. Schematic Diagrams

Schematic diagrams are the most common type and use standardized valve symbols to represent components. They focus on function rather than physical appearance, making them ideal for showing a valve’s role in a system. These diagrams are easy to read and provide a quick overview of the control loop.

3. Piping and Instrumentation Diagrams (P&IDs)

P&IDs are comprehensive drawings that show the entire process system. A control valve is just one of many components on a P&ID, which also includes pipes, pumps, sensors, and other instruments. This type of diagram shows the interconnectivity of all components, including the power unit and control systems.

How to Read a Control Valve Diagram

Reading a control valve diagram becomes straightforward with a systematic approach. By breaking it down, you can quickly understand the valve’s function and specifications. Follow these steps to interpret any diagram you encounter.

1. Identify the Valve Type

The first step is to identify the basic valve symbol. This symbol represents the valve body and tells you its general type. Different symbols are used for a gate valve, globe valve, ball valves, and valve butterfly configurations.

Each type valve has unique characteristics, and its symbol is the first clue to its function. For instance, a check valve symbol will show it only allows flow in one direction. Recognizing these basic shapes is the foundation of reading any schematic.

2. Locate the Actuator

Above the valve body symbol, you will find the symbol for the actuator. This tells you how the valve is automated. Common actuator types include diaphragm, piston, and electric motor actuators.

The symbol also indicates the power source, such as pneumatic or electric. Additional notations may specify if the valve fails open, closed, or in its last position upon loss of power. A solenoid valve symbol might be included as part of the actuator’s control mechanism.

3. Follow the Flow Path

Arrows on the piping lines indicate the intended direction of fluid flow. Tracing this path helps you understand the valve’s purpose within the larger process. The valve’s placement in the line provides context for its operation.

4. Check the Signal Lines

Examine the lines connecting to the actuator and positioner. These lines show how the valve is controlled. A dashed line usually indicates a pneumatic signal, while a solid line can represent an electrical or hydraulic connection, sometimes involving a hydraulic hose.

5. Note Any Additional Components

Look for other symbols attached to the main valve assembly. This could include a positioner, limit switches for open/close feedback, or a pressure relief device. A level switch symbol nearby could indicate the valve is part of a tank-filling application.

Here is a table outlining common valve symbols:

Valve Type	Symbol Description	Common Use
Gate Valve	Two triangles pointing toward each other with a vertical line between them, intersected by a T-shaped stem.	On/off isolation.
Globe Valve	Two triangles pointing toward each other with a solid black circle between them, intersected by a T-shaped stem.	Throttling and flow regulation.
Ball Valve	Two triangles pointing toward each other with an open circle between them, intersected by a T-shaped stem.	Quick on/off control.
Butterfly Valve	Two triangles pointing toward each other with a vertical line and a diagonal line through the center, resembling a butterfly.	On/off or modulating control in large pipes.
Check Valve	Two triangles pointing toward each other with a ‘Z’ or ‘N’ shape inside, and an arrow showing flow direction.	Preventing backflow.
Relief Valve	A basic valve symbol with an arrow pointing away from the side, indicating pressure release. Often connected to a spring symbol.	System over-pressure protection.
Diaphragm Valve	Two triangles pointing toward each other with a curved arc connecting them at the top.	Handling corrosive fluids or slurries.

Applications of Control Valve Diagrams

Control valve diagrams are indispensable across various stages of an industrial project’s lifecycle. Their clarity and detail support critical functions from initial concept to daily operation. They are foundational documents for managing process systems safely and efficiently.

1. System Design

During the design phase, engineers use P&IDs and control valve diagrams to lay out the entire process. These diagrams help in selecting the correct type of valve for each application. They also help specify pressure control valves or a pressure reducing valve where needed to manage system pressures.

The diagrams ensure proper integration of all components, from the main process lines to small utility connections. They are used to verify that the system design meets safety and operational requirements. This includes planning for scenarios involving high pressure or significant differential pressure across a valve.

2. Troubleshooting

When a process issue occurs, a control valve diagram is often the first document a technician consults. The diagram allows them to trace control signals and fluid paths to isolate the problem. It helps them understand the relationship between a valve and other instruments in the loop.

For example, if a tank level is incorrect, the technician can use the diagram to find the associated control valve. They can then check the signal from the controller, the air supply to the actuator, and the valve’s physical position. This systematic approach saves time and reduces downtime.

3. Maintenance Planning

Maintenance teams use diagrams to plan for both routine and emergency work. The diagram provides information on valve type, size, and connection type, allowing for the correct parts to be ordered. It also helps in developing safe work procedures for isolating equipment before maintenance.

4. Training

Control valve diagrams are excellent tools for training new operators and technicians. They provide a clear visual representation of how the process works and how the valves control it.
