The bellows seal globe valve is also called the bellows sealed stop valve. Through automatic rolling welding, a metal barrier is formed between the fluid medium and the atmosphere to ensure the zero leakage design of the valve stem.
The bellows seal globe valve adopts a bellows structure inside. 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 is 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.
Product features of bellow seal globe valve:
1. Reasonable product structure, reliable sealing performance, beautiful appearance;
2. Co-based hard alloy surfacing on the sealing surface, good wear resistance, corrosion resistance, anti-friction performance, long service life;
3. Valve stem tempering and surface nitriding treatment, with good anti-corrosion and anti-friction performance;
4. Double sealing of right-angle German standard bellows stop valve, more reliable performance;
5. Valve stem lifting position indication, more intuitive;
6. Parts material, flange and butt welding number size can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
