Pressure Sustaining Pilot Valve Model FP#3UL

 

This pilot valve integrates all the principal functions of a two-way control circuit into a single assembly.

It is a direct acting valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. When used in a pressure relief/sustaining circuit, the pilot modulates to open as upstream pressure rises above set point.

An integral needle valve acts as an upstream flow restrictor as well as a closing speed control.
