Overview

Check valves are used widely in pipelines conveying liquids, gases and steam. They prevent the fluid from back flow in a very simple manner. The only moving part in the check-valve is the check-valve is the disc with seal, hinged on the body to rotate freely, closing at an angle of 5°

Utility Priority

Check valves are designed to control the direction of flow while giving priority to specific utility lines in multi-source piping systems. Commonly used in water, gas, and industrial utility networks, these valves ensure that critical supply lines receive uninterrupted flow during pressure fluctuations or backup source activation. They help maintain system stability, prevent backflow, and support seamless switching between utility sources.Others Product
