mainly uses in the industrial water supply , sewage treatment plant water pump outflow point, prevents in the pipe network the medium adverse current.

light,easy to operate.High efficiency,high quality valve

Small volume,light weight,smaller resistance,resist weariness,long service life,good sealing and no noise in closing.

Check valves are opening and closing a borrow medium force automatically block medium of the valve upstream. Installed to prevent reverse flow in pipe
