[Bellows Sealed Globe Valve]——A design that forms a metal barrier between the fluid medium and the atmosphere through automatic roll welding to ensure zero leakage of the valve stem. The bellows globe valve uses a bellows structure. The lower end of the stainless steel bellows is welded to the valve stem through a stainless steel gasket to prevent the process fluid from corroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. Double seal design is adopted. If the bellows fails, the stem packing will avoid leakage. The bellows are welded to the stem to maintain stable operation performance, to avoid stem vibration caused by flap vibration. It is most suitable for pipelines with steam, flammable, explosive, thermal oil, high purity, toxic and other media.
