Pressure Reducing Servo Pilot Valve, Plastic PC-S-P

This pilot combines all principal functions of a 2-way control circuit with
elements of a 3-way control circuit. It is a direct acting pilot valve,
actuated by a pressure responsive diaphragm, which seeks to reach
equilibrium between hydraulic and set spring forces. A fully balanced
trim ensures high accuracy and stability. When used in a pressure
reducing circuit, the pilot modulates closed as downstream pressure
rises above setting.
The pilot’s unique internal design dynamically increases and decreases
the main valve response speed in direct proportion to the discrepancy
between actual and setting pressures.
