Description
Double union ball valves are designed to allow full removal of the valve body from a pipeline, making them ideal for applications where future maintenance, refurbishment or replacement may be required. With union connections on both sides, the valve can be demounted without cutting or disturbing the surrounding pipework. Manufactured from PVCu, these valves provide good chemical resistance and durability across a wide range of industrial and commercial fluid handling applications. The plain union ends are intended for solvent welding, creating strong, permanent joints when installed correctly.
A key feature of this valve is the locking end, which allows the torque on the internal ball to be adjusted to suit system pressure. Prior to installation, the locking end should always be checked and tightened if required, as insufficient torque can lead to leakage. For convenience, the handle can be removed and used as a spanner to tighten the locking end during setup or adjustment.
The ergonomically designed teardrop handle offers a secure grip and smooth operation, with a clear visual indication of valve position. As part of the economy range, these valves are batch tested on a 1 in 1000 basis, providing a cost-effective solution where full individual testing is not essential.
