Description
Designed for reliable shut-off and controlled drainage in PVC metric pipe systems, this single union ball valve provides a compact and practical isolation solution where full double-union removal is not required. The solvent weld connection ensures a secure, permanent joint, while the single demountable union allows for straightforward maintenance or downstream disconnection when both sockets are installed using the correct solvent cement and cleaner.
Commonly installed as an end-of-line isolation valve, this fitting is often referred to as a dump valve, making it particularly suitable for draining pipework, tanks, or manifolds during maintenance or system shutdowns. The smooth quarter-turn operation enables quick and positive flow control, even in restricted spaces.
Manufactured from high-quality PVCu and sealed with EPDM, the valve offers excellent resistance to corrosion, scaling, and a wide range of water-based fluids.
