Performance & Functions

The swing check valve adopts a built-in swing-arm structure. All the opening and closing parts of the valve are installed inside the valve body and not penetrate the valve body. Except for the gasket and seal ring in the middle flange, there is no leakage point, preventing the possibility of leakage of the valve. Swing check valve rocker arm and valve disc adopt a spherical connection structure, so that the valve disc has a certain degree of freedom within a 360-degree range, with appropriate micro-position compensation.
