Swing single plate wafer check valve

DN50-DN300 PN16 Swing single plate wafer check valve The swing check valve adopts a built-in rocker swing structure. All the opening and closing parts of the valve are installed inside the valve body, and do not penetrate the valve body, except for the sealing gasket and sealing ring for the middle flange. , There is no leakage point as a whole, preventing the possibility of valve leakage.
