3 – Pressure Sustaining Pilot 2 way


  • Integral needle valve
  • Internal or external pressure sensing
  • Differential pressure sensing
  • Direct pressure gauge installation
  • Optional materials of Stainless steel, NAB or Hastelloy
  • Optional high-pressure kit up to 30/45 bar


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 or sustaining circuit, 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.
