China High Quality Cn7m Check Valve Supplier – BS1868 Swing Check Valve – Guangwo Valve

GW BS1868 Swing Check Valve

BS1868 swing check valve prevents potentially damaging backflows to protect equipment like as pumps and compressors. The Non-return valves allow the flow of the fluid in one direction only and block reverse flows. It has the simplest design and operates via a metallic disc attached to a hinge at the top. when the fluid passes through a the swing check valve, then the valve is open. When a reverse flow occurs, the changes in motion as well as gravity help to close the disc, closing the valve and preventing backflows.
