Welded Bellows Globe Valve
Introduction:
The welded bellows globe valve can be divided into straight through type, angle type and direct current type according to the structure. Welded bellows sealed globe valves are manufactured by introducing advanced technologies at home and abroad, adopting metal bellows sealing technology, high-performance elastic metal bellows, and have a long expansion fatigue life. The double bellows seal globe valve adopts the design of bellows seal, which completely eliminates the disadvantage of quick aging and leakage of ordinary valve stem packing seal. It not only improves the energy efficiency, increases the safety of production equipment, reduces maintenance costs and frequent maintenance, but also provides a clean and safe working environment.
Product features:
1. Double sealing design (bellows+packing) If the bellows fails, the valve stem packing will also avoid leakage and meet international sealing standards.
2. No fluid loss, reduce energy loss and improve plant equipment safety.
3. Long service life, reduce replacement times and reduce operating costs.
4. Durable bellows seal design ensures zero leakage of the valve stem and provides maintenance free conditions.
5. PTFE soft sealing material is adopted for gas medium valve seat to improve the sealing performance of the valve.
6. High temperature resistance and 425. (: The valve seat is hard sealed with conical surface to achieve air tightness and zero leakage.
