Pump Control Valve Flange From 2

Pump Control Valve is installed on the pump discharge. It opens slowly on start-up of the pump, until it is fully open, and gradually closes prior to the pump shut-off, preventing pressure surges caused by a rapid change of water velocity in the discharge pipe.
We can adjust both opening and closing speeds of the valve. A limit switch that is assembled on the main valve bonnet is connected to the pump control panel and switches off the pump motor when the valve is completely closed. In case of a power or pump failure, the valve instantly closes, performing as a fast-reacting check valve. The main valve is "normally closed" (N.C.).
