Product Details

Product overview
The national standard swing check valve adopts built-in rocker swing structure, all opening and closing parts of the valve are installed inside the valve body, do not penetrate the valve body, except for the sealing gasket and sealing ring of the middle flange part, the whole has no leakage point, eliminating the possibility of valve leakage. The rocker arm and disc connection adopts a spherical connection structure, so that the valve disc has a certain degree of freedom within 360 degrees, and there is appropriate micro position compensation. Widely used in chemical, metallurgy, pharmaceutical and other fields.
