The Working Principle Of Wedge Gate Valve

The opening and closing part of the wedge gate valve is the gate plate, the movement direction of the gate plate is perpendicular to the direction of the fluid, the wedge gate valve can only be fully open and fully closed, not cooperative regulation and throttling. Wedge gate valves generally open and close by moving the stem up and down with the rotating handwheel. There are two kinds of clear stem wedge gate valve and dark stem wedge gate valve. The stem moves up and down and the stem nut is fixed. Dark stem gate valve is fixed stem, stem nut moves up and down to complete the opening and closing.
