bellow seal globe valve
Product Introduction
Bellows globe valve is also called bellows seal globe valve. It is welded by automatic seam welding to form a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem. The bellows stop valve adopts a bellows structure internally, and 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 will prevent leakage if the bellows fails and the valve stem packing fails. The bellows is welded to the valve stem to maintain stable operating performance and avoid valve stem vibration due to valve plug vibration. Most suitable for pipelines with steam, flammable, explosive, thermal oil, high purity, toxic and other media.
Bellows seal globe valve product features:
1. The product has reasonable structure, reliable sealing performance and beautiful appearance;
2. The sealing surface is overlayed with co-based carbide, which is wear-resistant, corrosion-resistant, anti-friction and has a long service life;
3. The valve stem is tempered and surface nitrided, which has good anti-corrosion and anti-friction properties;
4. The right-angle German standard bellows stop valve is double sealed and has more reliable performance;
5. The valve stem lifting position indication is more intuitive;
6. Part materials, flange and butt weld number sizes can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
Our advantages
Core components
1. Double sealing design (bellows + packing). If the bellows fails, the valve stem packing will also avoid leakage and comply with international sealing standards.
2. No fluid loss, reducing energy loss and improving factory equipment safety
3. Long service life, reducing maintenance times and operating costs
4. The sturdy and durable bellows seal design ensures zero leakage of the valve stem and provides maintenance-free conditions.
5. The gas medium valve seat adopts PTFE soft sealing material to improve the sealing performance of this valve.
6. The valve seat with high temperature resistance ≤425℃ adopts cone surface hard sealing. Achieve air tightness and zero leakage
