NON-RISING STEM GATE VALVES
Non Rising Stem Gate Valve Drawing
Non rising stem gate valvesis also called rotary stem gate valve (also called non rising stem wedge gate valve). The valve stem nut is set on the gate, and the handwheel rotation drives the valve stem to rotate, so as to lift the gate. Generally, there are trapezoidal threads at the bottom end of the valve stem. Through the thread at the bottom end of the valve and the guide groove on the valve disc, the rotary motion is changed into linear motion, that is, the operating torque is changed into the operating thrust. When the valve is opened, when the lifting height of the ram is equal to 1:1 of the valve diameter, the fluid channel is completely unblocked, but in operation, this position cannot be monitored. In actual use, the apex of the valve stem is used as the mark, that is, the position that can not be opened is used as its full open position. In order to consider the lock phenomenon of temperature change, usually in the open to the top position, and then back 1 / 2 ~ 1 turn, as the full open valve position. Therefore, the full open position of the valve is determined by the position of the RAM (i.e. stroke).

The Features of Non Rising Stem Gate Valves
The advantages of non rising stem gate valves: the height of the gate valve always remains unchanged, so the installation space is small. It is suitable for gate valves with large diameter or limited installation space. This kind of structure should be equipped with opening and closing indicator to indicate the opening and closing degree.
The disadvantage of non rising stem gate valves: the stem thread is not only unable to be lubricated, but also directly subject to medium erosion, easy to damage.
