Description
The ABS Air Release Valve is designed to automatically discharge trapped air from pressurised pipework systems, helping to maintain efficient flow and protect system components from air-related issues such as noise, cavitation and pressure loss.
Manufactured from durable ABS and fitted with EPDM seals and a stainless steel spring mechanism, the valve opens to release accumulated air and closes once liquid reaches the valve, ensuring smooth and reliable system operation. Its compact construction allows it to be installed easily within ABS pipework systems, even where space is limited.
With imperial plain ends, the valve is solvent welded into place using standard ABS solvent cement and cleaner, providing a secure and permanent joint suitable for long-term service.
