Bermad - Model 2 - Brass - 2 Way Pressure Reducing Pilot

This pilot integrates all principal functions of a 2-way control circuit in 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-reducing circuit, the pilot modulates closed as downstream pressure rises above the set point. An integral needle valve acts as an upstream flow restrictor as well as a closing speed control.
