Pressure Relief Valves

Alpeco are the UK distributors of OCV Pressure Relief Valves

The OCV 108 Pressure Relief / Back Pressure control valve’s main function is the maintain the line pressure in a liquid piping systems within relatively narrow limits.

Installed in the main flow line, the standard Model 108-2 acts as a back pressure or pressure sustaining valve. In this configuration, the valve maintains a constant upstream pressure regardless of fluctuating downstream demand. When used in a bypass line, the same model will function as a relief valve, protecting the system against potentially damaging surges.
