Model 700
Pressure Reducing Valve

Establishing various pressure zones is one of the most common means of achieving balance in fluid transmission and distribution networks. Pressure Reducing Valves (PRV) force the dynamic parameters of the supply system into a constant predetermined delivery pressure. An active PRV, through definition of minimum required pressure at each pressure zone’s critical point, enables continuous readjustment of delivery pressure. This allows the system to work at a lower average pressure.

The Model 720 Pressure Reducing Valve is a hydraulically operated, diaphragm actuated, control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure.
