Bellow Sealed Globe Valve For Ammonia feature
1. The hydraulically formed bellows forms the first seal, Bellow Sealed Globe Valve for Ammonia is the key component of the metal bellows, the lower end and the stem assembly are automatically welded by welding, the upper end and the connecting plate are automatically rolled and welded, in the fluid medium and the atmosphere. A metal barrier is formed to ensure zero leakage of the valve stem.
2. The multi-stage PTFE packing combination in the stuffing box forms a second seal on the bellows, which increases the reliability of the seal.
3. The multi-stage PTFE sealing material is used in the upper sealing device to form a combined seal to ensure that the packing box has no medium leakage during the service life, which eliminates the weak seal of the ordinary valve packing box, the medium is easy to leak, and even causes accidents. may.
4. The middle flange adopts the groove sealing structure to ensure the reliable sealing of the middle flange even in the case of fluctuation of the pipeline pressure.
5. The sealing pair matching structure adopts cone and flat type, and the seal is automatically compensated to achieve double insurance effect, stable sealing performance, no adhesive wear and long service life.
