Discharge Priming Valves
Berkeley Automatic Discharge Priming Valves are designed to be specifically used in pump priming and are necessary for proper pump operation. The priming valve is installed on the discharge side of an irrigation pump and must provide an air tight seal. This spring operated check valve then allows water to fill the volute cavity before the pump is started. Once the pump is fully primed and started, the speed increases which automatically opens the valve. The spring will hold the valve open while the pump is in operation. When the pump shuts down, the priming valve will close automatically and hold the prime in the pump and suction line.
