The opening and closing part of the wedge gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The wedge gate valve can only be fully opened and fully closed, and is not suitable for regulation and throttling. Wedge gate valve generally completes the opening and closing of the valve by moving the valve stem up and down with the rotating handwheel.
There are two kinds of rising stem wedge gate valve and Non rising stem wedge gate valve. The rising stem wedge gate valve moves the valve stem up and down, and the valve stem nut is fixed. The Non rising stem gate valve is fixed by the valve stem, and the valve stem nut moves up and down to complete the opening and closing.
