Bermad - Model PC-20-P - 2 Way Reducing Pilot

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 the set point. An internal restriction acts as an upstream flow restrictor
