Useful Info:

These pressure loading and relief valves from Durapipe operate to provide multiple functions within a single valve body offering both pressure loading and pressure relief within pipework systems. They are simple and easy to use and designed with attached labels on the valve to indicate installation directions.

The pressure loading feature allows a back pressure to be built up within the pipe system of between 0-3 bar, whilst the pressure relief function can be set to between 0-10 bar to provide system protection and works by relieving system pressure once the flow of liquid exceeds the set pressure parameters.
