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.

Forged Steel Gate Valve API 602 Gate Valve Flanged Raised Face NPT Or BSPT Ends  B.W Or S.W Ends Solid Wedged Type Bolted Or Welded Cover API 6D & CE Certified Forged steel gate valves Glofa produced which sizes are 3â?³(DN80) and smaller, compared with castings, forged valve bodies offer the advantages of more uniform structure, greater density, higher strength integrity, enhanced dimensional characteristics and closer dimensional tolerances.Forged steel gate valve Glofa offered have superior properties of heat preservation and cold preservation, the valveâ??s bore diameter are same as the pipelines and the medium flows in straight lines, resulting in that the resistance force are small and could prevent the heat losing effectively, this type valve are better choice for the fluid which is easy to solidify and with higher viscosity Glofaâ?? forged steel gate valve is with wedged type sealing structure, it is sealed by the wedge compressing on the seat, this sealing type make it possible unaffected by the pipeline pressure difference. The forged steel gate valve Glofa design are with self-cleaning structure, the fluid flow through the valve along on the sealing surface in 360 , which could eliminate the crash to the seat by the fluid in high speed, also flush away the dirties on the sealing surface.
The metallurgical gate valve is installed on the combustion air, gas, cold air and flue gas pipes of the hot blast stove system, cutting off the medium. In general, the gate works only in the full open or full off state and is not suitable for use as an adjustment or throttle. Suitable for combustion air, gas, cold air and flue gas piping in blast furnace hot blast furnace system Wedge block is arranged on both sides of valve body to realize forced sealing Cemented carbide sealing surface
