UPVC True Union Ball Check Valve

A True Union Ball Check Valve is a type of check valve designed to allow fluid flow in one direction while preventing backflow.
“True Union” means the valve has union connections on both ends, allowing for easy installation and removal without needing to cut or disassemble the entire pipeline.
Key Advantages
Durable & simple design – Fewer moving parts than swing check valves.
Easy maintenance – True Union design allows quick removal.
Low cracking pressure – Opens easily with minimal forward pressure.
Good for horizontal & vertical flow – Works in multiple orientations.
