Details Description
Ductile Iron Non Rising Stem Flange 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.
* Flange gate valves are commonly used in various industries to control the flow of fluids, such as water, oil, and gas. They offer a reliable and efficient way to start, stop, or regulate the flow through a pipeline. The choice between a rising stem and non-rising stem flange gate valve depends on the specific application requirements and the available space for installation.

Some special gate valve is used in slurry and powder product also such as knife gate valve
Advantages of Gate Valve
Gate valve provides good pressure drop during operation
Most of the gate valve can be used as bi-directional
They are suitable for high pressure and temperature application and required less maintenance
