DN50-DN600mm Rubber Disc F6 Check Valve For Water H44H ​​swing check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve whose main function is to prevent the backflow of the medium, the reverse rotation of the pump and the driving motor, and the

DIN Ductile Iron PN10 PN16 DN100 Ball Check Valve Flanged product description ball check valves are self-cleaning and with full bore. The ball rotates during operation eliminating the risk of impurities getting stuck on the ball. The full and smooth bore ensures full flow with low pressure loss and eliminates the risk of deposits at the bottom. ball check valves are available with flanges and internal threads. They are delivered with NBR lined ball as standard and optionally

Factory Piece Double Way Ductile Iron swing Check Valve DN50-DN400 PN10/16 product description Check valves may also be used on lines supplying auxiliary systems where pressure may rise above system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis). The purpose of this type of valve is to allow the medium to flow in only one direction and prevent flow in the opposite
