Pressure Reducing Pilot Valve Model PC-20-P

This pilot integrates all principal functions of a 2-way control circuit in a single assembly. It is a direct acting pilot valve, actuated by a pressure responsive diaphragm, which seeks to reach equilibrium between hydraulic and set spring forces. When used in a pressure reducing circuit, the pilot modulates closed as downstream pressure rises above set point. An internal restriction acts as an upstream flow restrictor.

Features and Benefits

  •  Internal or external upstream flow restrictor
  •  Internal or external pressure sensing
  •  Differential pressure sensing


Typical Applications

  •  Pressure Reducing Valves sizes 11/2-4” (Standard model #PC-20-P)
  •  Closing Surge Control (additional feature 49) for sizes 11/2-4” (Modified to external pressure sensing PC-20-P-R)
