PRESSURE SUSTAINING PILOT VALVE IR 3PBL

This is a direct acting Pilot 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 sustaining circuit, the pilot modulates closed as downstream pressure drops below set point.
