The opening and closing part of the Non-rising Stem Stainless Steel Gate Valve is a gate. The movement direction of the gate is perpendicular to the direction of the fluid, which can be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used model gate valve form a wedge. The wedge angle varies with valve parameters, usually 50, and 2°52``'' when the medium temperature is not high. The manufacturer of Non-rising Stem Stainless Steel Gate Valve tells you that the gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce slight deformation to improve its manufacturability and make up for the angle of the sealing surface. This kind of gate is called elastic gate for the deviation produced in the process of processing.

Non-rising Stem Stainless Steel Gate Valve is also called rotating stem gate valve (also called dark stem wedge gate valve). The valve stem nut is set on the gate. The rotation of the handwheel drives the rotation of the valve stem to lift the gate. There is usually a trapezoidal thread at the bottom end of the valve stem. The thread on the bottom end of the valve and the guide groove on the disc will rotate the gate. It becomes linear motion, that is, the operating torque is changed to operating thrust. The manufacturer of Non-rising Stem Stainless Steel Gate Valve tells you that when the valve is opened, when the lift height of the gate is equal to 1:1 times the valve diameter, the fluid passage is completely unblocked, but this position cannot be monitored during operation.
In actual use, the apex of the valve stem is used as the mark, that is, the unmovable position, as its fully open position. The manufacturer of Non-rising Stem Stainless Steel Gate Valve tells you that in order to take into account the temperature change, the lock phenomenon occurs. Usually, when the valve is opened to the top position, it is reversed 1/2~1 turn as the position of the fully open valve. Therefore, the fully open position of the valve is determined by the position of the gate (that is, the stroke).
