Product parameters
The stop valve is also known as the cut-off door. The opening and closing parts move up and down the center line of the sealing surface of the valve seat to make the valve open and close. The path is perpendicular to the seal, so the sealing surface is frictionless in the process of opening and closing, and the service life is long
