ANSI Bellows Globe Valve
Introduction:
The bellow stop valve is of corrugated structure inside, and the lower end of the stainless steel bellow 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 bonnet to form a static seal. Double sealing design is adopted. If the bellows fails, the valve stem packing will also avoid leakage. The bellows is welded to the valve stem to maintain stable operation performance and avoid valve stem vibration caused by valve plug vibration. It is suitable for pipelines with steam, flammable, explosive, heat transfer oil, high-purity, toxic and other media.
