The OCV Series 94 check valve is a simple on-off valve that opens to allow forward flow when inlet pressure exceeds outlet and closes tightly to prevent back flow when outlet pressure exceeds inlet pressure.

Equipped with controlled opening speed pump discharge pressure is gradually introduced to the system. Pump is protected from reverse flow.
Used in conjunction with the Model 126, the Series 94 provides start up and shutdown surge protection for deep well pumps.
The Model 94-1 consists of the following:
For the most comprehensive procedure in sizing Series 94 control valves, it is best to use our ValveMaster software or the guidelines shown here in conjunction with the Performance Charts in the Engineering Section of the OCV catalog.
Check valves are nearly always line sized, however there are some limitations. Model 94, with no speed controls, should be used only where flow velocities will not exceed 6 ft/sec. Check valves with speed controls (94-1, 94-2, etc.) may be used at flow velocities up to 15 ft/sec.
Series 94 check Valves are available with various combinations of speed controls. Select the desired features and then the model number.
This chart shows only a sample of those most often specified valves. Consult the factory for specific data on the model you selected.
A routine inspection & maintenance program should be established and conducted yearly by a qualified technician. Consult our factory @ 1-888-628-8258s for parts and service.
