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.

Main features * Bolted body-bonnet design,seal welded & Valves with pressure seal bonnet * Bellows-sealed Gate and Globe valves available * Bolted body-bonnet joints provided with spiral-wound stainless steel gasket and graphite filler for maximum protection against leaks * Die-formed graphite inner packing rings and braided graphite end rings with Inconel wire reinforcement and corrosion inhibitor * T-head stem-disc connection of gate valve fully meets strength requirements of API 602 and API 598 * Rolled ACME thread on stem for smooth operation * Tapered shoulder on the stem for back seating * Self-aligning type gland assembly with stud-and-nut tightening * Integral hard-faced body seat for globe and check valves * Spring-loaded disc on check valves suitable for no horizontal applications too * Gate and globe valves can be offered with electrical actuators * Austenitic SS forging for body and bonnet of Cryogenic valves, resulting in excellent impact strength, minimal heat loss and resistance to corrosion * Valves can be offered to NACE MR-0175 and other special NACE requirements

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
