Pressure Sustaining Pilot Valve Model #3PB

This 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.  
Product Features & Benefits
  • Internal or external pressure sensing
  • Differential pressure sensing
  • Direct pressure gauge installation
Typical Product 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)
