H44H-16/25COverview of Cast Steel Swing Check Valve

Cast steel swing check valve, also known as swing flange check valve, is an automatic valve that automatically opens and closes by the force generated by the flow of the medium itself in the pipeline.The swing check valve adopts an internal rocker arm swing structure, and all the opening and closing parts of the valve are installed inside the valve body, without penetrating the valve body. Except for the sealing gasket and sealing ring used in the middle flange, there is no external leakage point as a whole, which eliminates the possibility of valve leakage. The swing arm and valve disc connection of the rotary check valve adopt a spherical connection structure, which enables the valve disc to360There is a certain degree of freedom within the range of degrees, with appropriate micro position compensation.
