Description
The Model 723 Pressure Sustaining and Reducing Valve is a hydraulically operated, diaphragm actuated control valve with two independent functions. It sustains minimum pre-set upstream pressure, regardless of fluctuating flow or varying downstream pressure. And, it prevents downstream pressure from rising above maximum pre-set, regardless of fluctuating flow or excessive upstream pressure.
