Pressure Sustaining Pilot Valve Model #3PB

Pressure Sustaining Pilot Valve Model #3PB

WW-Model_3PB_BIG_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 valve sizes 11/2-4” (Standard model #3PB).
  • Differential Pressure sustaining valve sizes 11/2-4” (Modified to differential sensing #3PB-D)
