Pressure Reducing Pilot Valve WW #2PBL

This is a direct acting valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. Fully balanced trim ensures high accuracy and stability. When used in a pressure reducing circuit, the pilot modulates closed as downstream pressure rises above set point.

Product Features & Benefits
  • Internal or external pressure sensing
