Product Details

Ductile Iron Swing Check Valve


Ductile iron swing check item 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 at the middle flange, There is no leakage point as a whole, preventing the possibility of valve leakage. The connection between the rocker arm and the valve clack adopts a spherical connection structure, so that the valve clack has a certain degree of freedom in the range of 360 degrees, and there is an appropriate trace position compensation. It is widely used in many fields such as chemical industry, metallurgy, pharmacy, hydraulic power and so on.
