Pressure Sustaining Valves

  • Pressure Sustaining Valve

Applicable Standard

In many liquid piping systems, it is vital that line pressure is maintained within relatively narrow limits. This is the function of the Pressure Sustaining Valve of the Hyper Valve. Installed in the main flow line, the standard model acts as a backpressure 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.
