Gate valve closed, the sealing surface can only rely on media pressure to seal, that is, relying on the media pressure will be the sealing surface of the gate to the other side of the valve seat to ensure that the sealing surface of the seal, which is self-sealing. Most of the gate valve is a mandatory seal, that is, when the valve is closed, to rely on external forces to force the gate to the valve seat to ensure that the sealing surface of the seal.

Gate valve gate with the stem together for linear movement, called the lifting stem gate valve (also called open stem gate valve). Usually on the lifting stem has trapezoidal threads, through the nut at the top of the valve and the valve body on the guide groove, the rotary motion into a straight line, that is, the operating torque into the operating thrust.
