Bellows globe valve

The bellows globe valve is also called the bellows seal globe valve. Through automatic roll welding, a metal barrier is formed between the fluid medium and the atmosphere to ensure the design of zero leakage of the valve stem.
Bellows globe valve adopts bellows structure, stainless steel bellows lower end is welded on the valve stem to prevent process fluid erosion of the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. The use of double sealing design if the bellows failure valve stem packing will avoid leakage, bellows welded to the valve stem to maintain stable operating performance, to avoid the valve plug vibration caused by the valve stem vibration. The most suitable for steam, flammable, explosive, heat transfer oil, high purity, toxic and other media on the pipeline.
