The bellows seal globe valve adopts a bellow structure inside. 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. A double seal design is adopted. If the bellows fails, the stem packing will also avoid leakage. Bellows are welded on the valve stem to keep stable operation performance and avoid vibration of valve stem caused by vibration of valve disc. It is most suitable for pipelines with steam, flammable, explosive, heat transfer oil, high purity, toxic and other media.
