Durapipe LR Pressure Loading/Relief Valve

These PVCu pressure loading and relief valves from Durapipe are designed to provide multiple pressure control functions within a single, compact valve body. By combining both pressure loading and pressure relief capabilities, they offer a practical and efficient solution for managing pressure conditions within liquid pipework systems.

The pressure loading function allows a controlled back pressure of between 0 and 3 bar to be maintained within the system, helping to stabilise flow and support downstream equipment. In addition, the pressure relief function can be set between 0 and 10 bar, providing protection by relieving excess system pressure once the set threshold is exceeded.

Manufactured from high-quality PVCu with EPDM seals, these valves offer excellent chemical resistance and reliable performance across a wide range of applications. Clear directional labelling on the valve body ensures correct installation, while the system-matched design makes them ideal for integration into PVCu pipework systems used in industrial, water treatment and process environments.
