The Model FP 436 Differential Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated, control valve that sustains minimum pre-set, differential pressure between two points regardless of fluctuating flow or varying upstream pressure.
Features:
Hydraulically powered valve design – Closes drip tight time after time – Eliminates jamming problems
Hydro-efficient body design – Wide rangeability – Unrestricted flow path
One-piece molded single moving part No maintenance required
Operation The Model FP 436 Differential Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated, control valve that sustains minimum pre-set, differential pressure between two points such as pump suction and discharge, filter upstream and downstream, etc.
