Bellows globe valves, also known as bellows seal globe valves, are automatically welded to form a metal barrier between the fluid medium and the atmosphere to ensure stem leakage is zero. The bellows globe valve is constructed with bellows inside. The lower end of the stainless steel bellows is welded to the stem to prevent the stem from being corroded by process fluid. The other end is placed between the body and the bonnet to form a static seal. The double seal design also prevents leakage if the bellows fail the stem packing. The bellows are welded to the stem to maintain stable operating performance and prevent stem vibration due to plug vibration. Most suitable for steam, inflammable, explosive, heat conduction oil, high purity, toxic and other medium pipeline.
