OCV 125-7, a booster pump control valve, shall function to eliminate the surges from starting and stopping the pump. The valve will be closed when the pump is started. It will open slowly, gradually introducing flow into the line. When the pump is signaled to stop, the pump control valve will close slowly while the pump continues to run. As the valve approaches the full closed position, the valve stem will trip a limit switch mounted on the valve. The limit switch will then shut down the pump. Opening and closing speeds are independently adjustable. In the event of a power failure while the pump is running, the valve will close quickly by means of its lift check feature to prevent back flow. The valve is primarily designed for use with centrifugal booster pumps and can also be used on well pumps with relatively shallow lifts where the pump design permits starting against a closed valve. Because of its lift check feature, the valve is ideally suited to those pumping applications where little or no back flow can be tolerated.
