Ductile Iron Non Rising Stem Flange Type Gate Valve

Ductile Iron Non Rising Stem Flange Type Gate Valve


There is no upward movement of the stem in a non-rising stem type. The valve disk is threaded internally. The disc travels along the stem like a nut when the stem is rotated. You can see the image. In this type of valve, stem threads are exposed to the flow medium. Therefore, this design is used where space is limited to allow linear stem movement, and the flow medium does not cause erosion, corrosion, or wear and tear to stem material.  This type of valve also known as insider screw valve.
