Manual Non Rising Stem Gate Valves

Manual Non Rising Stem Gate Valves
Product Introduction:
Manual Non Rising Stem Gate Valves 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. Usually there is 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.

Description
Technical Parameters

Production

Manual Non Rising Stem Gate Valves : The stem nut is in the valve body and is in direct contact with the medium. When opening and closing the gate, it is realized by rotating the valve stem. The advantage of this structure is that the height of the gate valve always remains the same, so the installation space is small, and it is suitable for gate valves with large diameters or restricted installation space.
