Pilot Solenoid Valves Introduction

Pilot solenoid valves use the differential pressure of the medium over the valve ports to open and close. Also known as servo-assisted solenoids, these valves provide high flow rates and can operate at higher pressure and temperature ranges, with lower power consumption.

Pilot Solenoid Valves Feature

  • Excellent for very large flow.

  • Pressure assists valve operation.

  • Needs minimum pressure differential.

  • More economical for higher flow values

  • Lower electrical power level.

Characteristic:

1.Pilot operated diaphragm construction with less power consumption for longtime working;
2. Applied to pressure system opened from 0.3 bars;
3. Lifespan can be at 1 million cycles.

Pilot Solenoid Valves Application

Pilot solenoid valves are used as pilot operators for Air Operated Valves (AOVs) used in nuclear power plants. In a typical application, these air pilot valves feed and exhaust air pressure to the air actuator of the process valve (AOV) thus opening or closing the process valve.
