PVCu Air Release Valve Metric

This PVCu air release valve is designed to automatically discharge trapped air from pressurised pipelines, helping to maintain efficient flow, reduce pressure losses and prevent air-related system issues such as cavitation and flow restriction. By continuously venting air pockets as they form, the valve supports smoother system operation and improved hydraulic performance.

Manufactured from unplasticised PVC, the valve offers excellent corrosion resistance and long service life in water and chemically compatible fluid systems. The internal non-return mechanism ensures controlled air discharge while preventing fluid escape during normal operation. EPDM seals are supplied as standard, providing reliable sealing performance across the full operating temperature range.

Designed for vertical installation only, the valve features solvent-weld union ends that allow secure integration into PVCu pipework using solvent cement. It should be installed at the highest point in the system. The union design also allows the valve to be easily removed for inspection or maintenance. With no metal parts in contact with the fluid, the valve is suitable for corrosive environments and marine applications where material compatibility is critical.
