Pilot operated solenoid valves are a type of valve that uses a small pilot valve to control the flow of a larger main valve. The pilot valve is activated by an electrical signal, which in turn opens or closes the main valve. This design allows for the control of high flow rates and pressures with relatively low power consumption.
Characteristics
– Efficiency: Uses less power to operate compared to direct acting valves.
– Pressure Range: Can handle higher pressure differentials, making them suitable for various applications.
– Size: Typically larger than direct acting solenoid valves due to the additional components.
– Response Time: Generally slower than direct acting valves because of the pilot mechanism.
Examples
– Hydraulic systems: Often used in hydraulic machinery where high flow rates are needed.
– Pneumatic systems: Common in applications requiring the control of compressed air.
– Irrigation systems: Used to manage water flow in agricultural settings.
