Large Diameter non-rising stem gate valve

A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions.

The difference between rising stem gate valve and non-rising stem gate valve:

Rising stem gate valves have the threads external to the valve body. The gate valve stem is moving up when the valve is opening. Rising stem valves are usually made from cast or forged steel while non rising stem valves are more typically brass, bronze or cast iron.

The stem nut will rise upward when opening valve , it will move up with gate and open the valve, thus unlocking the pipeline. The stem nut will move down when closing valve, so will the gate. Meanwhile, the valve will be closed, the pipeline locked.


The figure of valve has no change when opening or closing valve.Small installation space and low cost.


Gate valves are used in many industrial applications including the oil and gas industry, pharmaceuticals, manufacturing, automotive, and marine. Non-rising stem gate valves are very popular on ships, in underground applications, or where vertical space is limited because they don't take up extra space.
