With the continuous improvement of high-tech development, valve conditions are also getting higher and higher. New valve products continue to enter the market, the upgrade of drive mode, changes of structures as well as temperature and pressure corrosion on the material requirements of the check valve, have improved respectively. Check valve relies on the flow of the medium itself to automatically open and close the valve flap. Check valve is an automatic valve, its main role is to prevent media backflow and the pump and drive motor reversal, together with the release of container media.

 Sanitary Check Valve with Butt-weld Ends


It includes swing check valve and lift check valve. A Swing check valve has a hinged hinge mechanism and a flap-like flap freely rests against the slanted seat surface. Lift check valve then has a flap located on the valve seat sealing surface. Depending on the conditions of use, the valve disc can be of all-metal construction or it can be in the form of a rubber gasket or rubber ring inlaid on the valve disc holder. The pressure through the lift check valve is larger than that of the swing check valve, but the flow check of the swing check valve is limited. With the continuous upgrade and change of the piping system, the traditional check valve has not reached the demand of the modern market. In recent years, many new check valve models have been born.
