Bellows Seal Globe Valve
The inner of the bellows seal globe valve adopts a bellows structure, and the bottom end of the stainless steel bellows is welded on the stem, to prevent the fluid from eroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. Adopting double seal structure, if the bellows fails, the stem packing can be avoided leakage. This kind of globe valve is suitable for pipelines of steam, flammable, explosive, heat transfer oil, high purity, toxic and other medium.
