The opening and closing of the stainless steel gate valve is the gate, the direction of movement of the gate and the direction of the fluid are perpendicular to each other. In addition, stainless steel gate valve can only play the role of full open and fully closed, not as a function of regulation and throttling.

The working principle of stainless steel gate valve

Stainless steel gate valve with the stem with a straight line movement, called the lift bar stainless steel gate valve (also called the stem stainless steel gate valve). Generally in the lift bar will have trapezoidal thread, through the top of the valve nut and the valve body on the guide groove, the rotary motion into a linear motion, that is, the operating torque into the operating thrust. The sealing surface of the stainless steel gate can be sealed only by the pressure of the medium, that is, by means of the medium pressure to press the sealing surface of the gate to the other side of the valve seat to ensure that the sealing surface seal, which is self-sealing. Most of the stainless steel gate valve is forced to seal, that is, when the valve is closed, it is necessary to rely on external force to push the gate pressure to the valve seat to ensure that the sealing surface sealing.
