The Forged Steel Compact Globe Valve is a high-performance fluid control device, precision-engineered from premium forged steel material. It combines throttling and shut-off functions in one unit. Designed specifically for high-pressure and high-temperature applications, it features compact construction, reliable sealing, and extended service life, making it ideal for demanding conditions in petroleum, chemical, power, and other industries.
The cryogenic butterfly body can be provided in twostructural forms, namely flange connection and butt.welding connection (both with inspection ports). The body with inspection ports can replace the valveinternals online, making maintenance work extremelysimple, which is conducive to the rational use ofresourcesand saving maintenance costs.The extended valve cover + drip tray design ensures thatthe temperature at the stuffing box is above zero degrees!so that the connection between the stuffing and the stemwill not freeze and lock.
The DBB Ball Valve (Twin Ball) requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
