Bellows globe valves, also known as bellows sealed globe valves, form a metal barrier between the fluid medium and the atmosphere through automatic roll welding, ensuring a zero leakage design of the valve stem.
Bellows globe valves, also known as bellows sealed globe valves, form a metal barrier between the fluid medium and the atmosphere through automatic roll welding, ensuring a zero leakage design of the valve stem. The interior of the bellows stop valve adopts a bellows structure, and the lower end of the stainless steel bellows is welded to the valve stem to prevent 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. Adopting a dual sealing design, 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. Most suitable for pipelines with media such as steam, flammable, explosive, heat transfer oil, high-purity, toxic, etc.
Features of corrugated pipe globe valves:
1. The product has a reasonable structure, reliable sealing performance, and beautiful appearance.
2. The sealing surface is welded with Co based hard alloy for wear resistance, corrosion resistance, good friction resistance, and long service life.
3. The valve stem is quenched and tempered with surface nitriding treatment, which has good corrosion resistance and friction resistance.
4. The right angle German standard corrugated pipe globe valve has double sealing, providing more reliable performance.
5. The valve stem lifting position indication is more intuitive.
6. The material of the parts, flange and welding number size can be reasonably selected according to the actual working conditions or user requirements, to meet various engineering needs.
