Pressure Regulator

What Pressure Regulators Are and How They Work

A pressure regulator can be an automatic valve or electrically controlled valve that is designed to keep the output at a uniform level regardless of the input pressure. Its main function or purpose is to adjust the pressure to keep the outlet pressure at a consistent level. 

Mechanical spring loaded pressure regulators can monitor downstream pressure whenever the set point is adjusted and its built-in spring is either released or depressed. The spring pushes down on the sensing diaphragm assembly whenever it is compressed, which can reposition the pilot plug to release upstream gas underneath the motor valve diaphragm. If the pressure exceeds the set point, the upstream pressure can close the pilot plug by pushing against the sensing diaphragm assembly. This allows the gas underneath the motor valve diaphragm to ultimately regulate the downstream pressure.

Electrical pressure regulators use a motor to open up or close down flow path of fluid.

The extra pressure (fluid) in these scenarios returns to the source for reintroduction into the system.

Pressure Regulator Advantages

Below are several advantages associated with pressure regulators:

• Helps decrease costs 
• Stabilizes the water/fluids pressure
• Reduces the risk of water/fluids leaks
• Ensures uniform water/fluids irrigation
• Extends equipment lifespan

Pressure Regulator Capabilities or Applications

Pressure regulators are capable of distributing water/fluids to crops without overwatering. Ultimately, this is important to the irrigation process because it can significantly improve the system’s efficiency by limiting water/fluid pressure fluctuations.

Besides farming, pressure regulators can also be used in several other applications, including sprinklers and sprayers. Sprinklers often perform best at a lower range and a pressure regulator valve makes it easy to keep the water/fluids pressure at a certain level to keep the water/fluids flow consistent and stable. Pressure regulators can also help prevent surges of pressure.

TlR Pressure Regulators

Consider the following aspects before selecting a pressure regulator:  

• Water/fluids pressure requirements
• Maximum inlet pressure
• Inlet and outlet connection size
• Other specific requirements

At Texas Industrial (TIR), we offer two plumbing sizes of electrically controlled butterfly pressure regulators to suit your needs:

PR. 1560B

This pressure regulator weighs 1 pound, has a flow range of 0-50 GPM, and can handle inlet pressure of up to 150 PSI max. It is housed with glass-filled nylon and has an inlet, Spade .25″ Male Tabs power connection type, and outlet connection of .75″ NPT Female.

PR. 1541B

This pressure regulator also weighs 1 pound, but can accommodate a higher flow range of 15-100 GPM. It is also housed with glass-filled nylon, can withstand a maximum pressure of 150 PSI, and has a Spade .25″ Male Tabs power connection type. However, it has a larger inlet and outlet connection of 1″ NPT Female.
