NON-RISING STEM GATE VALVES

Non rising stem gate valve drawing is 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.
