Introduction to bellows globe valve
Bellows globe valve is also called bellows seal globe valve, through automatic seam welding, a metal barrier is formed between the fluid medium and the atmosphere to ensure the design of zero leakage of the valve stem.
The bellows globe valve adopts a bellows structure inside, and the lower end of the stainless steel bellows is welded to the valve stem to prevent the process fluid from eroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. The double sealing design will avoid leakage if the bellows fails the stem packing. The bellows is welded to the valve stem to maintain stable running performance and avoid stem vibration caused by valve plug vibration. It is most suitable for pipelines of steam, flammable, explosive, heat transfer oil, high purity, toxic and other media.
