The bellows shut-off valve, also called the bellows seal shut-off valve, forms a metal barrier between the fluid medium and the atmosphere through automatic seam welding to ensure zero leakage of the valve stem.

 

  The inside of the bellows stop valve adopts a bellows structure, and the lower end of the stainless steel bellows is welded on 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. Double seal design If the bellows fails, the stem packing will also avoid leakage. The bellows is welded to the valve stem to maintain stable running performance and avoid the valve stem vibration caused by the valve plug vibration. It is most suitable for pipelines of steam, flammable, explosive, heat transfer oil, high purity, toxic and other media.
