DIN Globe Valve

WJ41H-16C/25C/40C/64C/100C

Bellows Stop Valve

Principle:

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.

Product advantages:

1. The metal bellows, the key component of the bellows seal globe valve, is automatically welded to the valve stem assembly at the lower end and to the connecting plate at the upper end, forming a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem.

2. The valve clack adopts plane design, and the sealing surface and medium form a flow line, with better sealing performance and longer service life.

3. Double sealing design (bellows packing) If the bellows fails, the valve stem packing will also avoid leakage and meet international sealing standards.

4. The valve cover is equipped with a grease fitting, which can directly lubricate the valve rod, nut and shaft sleeve, unlike the traditional way of adding lubricant only to the thread.

5. The ergonomically designed handwheel has a longer service life, easy and convenient operation, and is more safe and reliable.
