Bermad - Model 3 - Brass - 2 Way Sustaining / Relief Pilot

Bermad - Model 3- Product Image
Brand: Bermad
Category: Control Valves, PN16 Metal Pilots
Pressure Range:

1-16 Bar

Product Description

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 relief/sustaining circuit, the pilot modulates open as upstream pressure rises above the set point. An integral needle valve acts as an upstream flow restrictor as well as a closing speed control.


  • Integral needle valve
  • Internal or external pressure sensing
  • Differential pressure sensing
  • Direct pressure gauge installation

Typical Applications

  • Pressure Relief/Sustaining Valve (Standard model #3)
