Pressure Sustaining Pilot Valve Model #3HC

Pressure Sustaining Pilot Valve Model #3HC

WW-PressureReducingPilot3HC_GalleryThis 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 set point.



Features and Benefits

  • Internal or external pressure sensing
  • Differential pressure sensing
  • Direct Pressure gauge installation


Typical Applications

  • Pressure Relief/Sustaining Valves sizes 16-32” (Standard Model #3HC)
  • Differential Pressure Sustaining 16-32” (Modified to differential sensing #3HC-DR)
  • Surge Anticipating Valve sizes 6-14” as high pressure pilot (Modified to external pressure sensing #3HC-R)
