PRODUCT INFORMATION

Bermad 83 – High Sensitivity Pressure Sustaining Pilot

This pilot integrates all principal functions of a 2-way control circuit in a single assembly. It is a high sensitivity, direct acting valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force.

The pilot modulates 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.
