The rate of flow/pump suction control/check valve shall function to control or limit the flow rate, regardless of fluctuations in upstream or downstream pressure. It shall also prevent the pump suction vacuum from exceeding a predetermined value. If downstream pressure becomes greater than upstream pressure, the valve will close fully to prevent reverse flow.
The OCV 120-6PS has a wide range of applications - anywhere the flow rate and pump suction vacuum must be controlled or limited and reverse flow must be prevented. It therefore has an ideal application as a pump discharge control valve.
