Stem Gate Valve

Rising Stem Gate Valve has threads on the outside of the valve body. The gate stem moves up when the valve opens. Rising stem valves are usually made of cast or forged steel, while non-rising stem valves are more commonly brass, bronze or cast iron. This way you can visually track how open the valve is. For a rising stem gate valve, it is easy to tell whether the valve is open or closed by looking at the exposure of the valve stem. If the handle is flush with the pipe (no stem exposed), the valve is closed. The valve opens if a large amount of the stem is exposed Rising stem gate valve is characterised as having either a rising or a non-rising stem and are produced at HY Valves according to Korea standard KS B2350, and it can also according to DIN 3204 and DIN 3216 standards. Rising stem provides a visual indication of valve position. Non-rising stem gate valves are used where vertical space is limited. Rising stem gate valve must be used as fully open or fully closed position where the vibration does not exist in the system. As they are designed as this purpose gate valves are not suited for regulating flow.
