Model 120-55
Pressure Reducing Valve

Electric On/Off Control - Auto-Flush Valve

Establishing various pressure zones is one of the most common means to achieve 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.

Model 120-55 : The addition of a solenoid to the control loop enables the opening and closing of the valve by a remote controller. Pressure reducing performance is similar to that of Model 120. Model 120-55 operates with a variety of solenoid voltage ranges: 24VAC, 24VDC, Latch 9VDC, 12VDC.
