German standard corrugated pipe stop valve WJ41H/W is suitable for nominal pressure PN1.6-10.0MPa and working temperature - 20 ℃ - 425 ℃. The service life of the national standard bellows globe valve mostly depends on its core component - bellows. Bellows globe valve is a new type of bellows valve. Because the valve is designed with double seals, its sealing performance is more reliable than that of ordinary globe valves. The bellows with advanced technology in the world is used as the main technical component, which greatly improves the fatigue resistance and service life of the bellows stop valve. The use of the national standard bellows stop valve is applicable to the pipeline of the petroleum, chemical, pharmaceutical, chemical fertilizer, electric power industry and other working conditions, and is applicable to the heat transfer oil, toxic, flammable, highly permeable, polluting environment, radioactive fluid medium pipeline as the cut-off valve, and can also be used for regulation, It is the product to create a leak free factory.
Flange End Globe Valve,Size: DN80, Pressure PN25, ASTM A351 CF3M Stainless Steel, excellent anti-corrosion property for chemical, food and water treatment pipelines, applied for pipeline shut-off and flow regulation.
The Globe Valve is a forced seal valve. When the valve is closed, the disc pressure is increased to force the sealing surface not to leak. Globe Valve End Connect : Flange RF, NPT, Butt Weld. The medium flow of the Globe Valve enters the valve chamber from the top of the valve disc. Under the action of the medium pressure, the force of closing the valve is small and the force of opening the valve is large, and the valve is tight. The globe valve is mainly used as a cutting or regulating function. The stem opening or closing stroke of the stop valve is relatively short, and the cutting function is very reliable.
