Bellow Seal Globe Valve

The bellow seal globe valve is welded by automatic rolling welding to form a metal barrier between the fluid medium and the atmosphere, ensuring the zero leakage design of the valve stem. The internal structure of this valve is a bellows structure. The lower end of the stainless steel bellows is welded to the valve stem to prevent the process fluid from corroding 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 is adopted. If the bellows fails, the valve stem packing will also avoid leakage. The bellows are welded to the valve stem to maintain stable operating performance and avoid valve stem vibration caused by valve plug vibration. It is most suitable for pipelines with steam, flammable, explosive, thermal oil, high purity, toxic and other media.
