H74W Clamped Disc Check Valve has the advantages of simple structure, beautiful appearance, light weight, easy installation and so on. Mainly used in water supply system, petroleum, chemical industry, metallurgy and other industrial sectors for the installation of space limitations of the place is applicable.
Product Features
H74W butt-clamp disc check valve is an ultra-thin check valve with short structural dimensions and single flap design. Compared with traditional swing check valves, this series of valves has the advantages of no external leakage, can be installed in any position, good sealing performance, low linear vibration, low pressure drop and zero seat wear. The function of this type of valve is to allow the medium to flow in one direction only and to stop the directional flow. Usually this type of valve is automatic work, in one direction of flow of fluid pressure, the valve flap open; fluid flow in the opposite direction, by the fluid pressure and the valve flap of the self-gravity of the valve flap on the valve seat, thus cutting off the flow.
