Dirt Retainer Pressure Control Valve
Control Valve Function:
Provides safe closure to prevent leakage caused by reverse flow which may occur in situations of power outage, where the flow direction reverses in the force main. When entry pressure exceeds exit pressure (when the pump restarts) the valve opens automatically. When the checkvalve is mechanical it is not possible to have this kind of control during the on/off process. They generally contribute to the development of water impacts on the pipeline.
