Stem gate valve Most manual gate valve adopt forced sealing, that is, when the valve is closed, the gate must be forced against the seat by external force to ensure the tightness of the sealing surface. The gate valve of the gate valve moves linearly with the valve stem, which is called the lifting stem gate valve, also called the rising stem gate valve. In some gate valves, the stem nut is set on the gate, and the rotation of the handwheel drives the rotation of the valve stem to lift the gate. This kind of valve is called a rotating stem gate valve, or a dark rod gate valve.                             Connection                Threaded                                   Size &nb…
