Product Details

                                                  Double Seal Ball Valve


Basic info:

The double soft seal ball valve divides the valve body into asymmetrical left and right halves along the section perpendicular to the axis of the valve channel. It is mainly used in the pipeline to cut off, distribute and change the flow of the medium. Its pivot structure ensures accurate ball position. The standard valve seat adopts a spring structure, which pushes the valve seat to the sphere, ensuring good low-pressure sealing performance.
