Wafer Dual Plate Check Valve
The clamp lift check valve is a valve which is automatically opened and closed by the flow of the medium itself, and is used to prevent the reverse flow of the medium. It is also called a reverse check valve, a one-way valve, a countercurrent valve, and a back pressure valve. The check valve is an automatic valve. Its main function is to prevent the backflow of the medium, prevent the reversing of the pump and drive motor, and the discharge of the container medium. The check valve can also be used to supply pipelines where the pressure may exceed the system pressure. Check valves can be divided into swing check valves (with center of gravity rotation) and lift check valves (along the axis). Valves of this type should be installed horizontally in pipes.

Bronze Wafer Check Valve
The function of the Bronze Wafer Check Valve is to control the one-way flow direction of the valve in the pipeline, so as to prevent the backflow of the medium in the pipeline. The check valve belongs to the automatic valve type, and the opening and closing part is opened or closed by the force of the flowing medium. Check valve is only used for one-way flow of medium pipeline, to prevent media backflow, in order to prevent accidents. It is mainly used in petroleum, chemical, pharmaceutical, fertilizer, power and other pipelines.
