Description
The ABS Metric Pressure Loading / Relief Valve is a versatile, dual-function control valve designed to provide both pressure loading and pressure relief within ABS pipework systems. Manufactured by Durapipe, this innovative LR valve combines two critical pressure management functions into a single valve body, reducing system complexity and minimising the need to stock multiple valve types.
The valve operates using a spring-loaded diaphragm principle, with the set pressure adjusted via an integral adjuster screw located beneath the red protective cap. Depending on installation orientation, the valve can be configured to either:
- Build back pressure within a system (pressure loading)
- Protect downstream equipment by relieving excess pressure (pressure relief)
Clear flow direction arrows and attached labels on the valve body make correct installation straightforward, helping to prevent installation errors on site.
Union connections allow the valve body to be removed easily for inspection or diaphragm replacement without cutting the pipework. Metric plain ends are designed for solvent welding using ABS solvent cement and cleaner, ensuring full compatibility with ABS metric pipe and fittings.
Key Features & Benefits
