Bellows globe valve is also called bellows seal globe valve. Through automatic seam welding, a metal barrier is formed between the fluid medium and the atmosphere to ensure the design of zero leakage of the valve stem. The bellows globe valve adopts a bellows structure inside, and 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. The double sealing design will avoid leakage if the bellows fails the valve stem packing. The bellows is welded to the valve stem to maintain stable operation performance and avoid the valve stem vibration caused by the valve plug vibration. It is most suitable for pipelines of steam, flammable, explosive, heat transfer oil, high purity, toxic and other media.

Bellows globe valve product features:

1. Reasonable product structure, reliable sealing performance and beautiful appearance;

2. The sealing surface is surfacing with Co-based cemented carbide, which has good wear resistance, corrosion resistance, good friction resistance and long service life;

3. The valve stem is quenched and tempered and surface nitrided, with good anti-corrosion and anti-friction properties;

4. Double sealing of right-angle German standard bellows globe valve, more reliable performance;

5. The valve stem lifting position indication is more intuitive;

6. Parts material, flange and butt welding number and size can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
