A bellows seal globe valve boasts high performance elastic metal bellows, which are manufactured by introducing foreign advanced technology and adopting foreign metal bellows sealing technology. Its fatigue life is particularly long. The design of bellows seal completely eliminates the shortcomings of quick aging and easy leakage of ordinary valve stem packing seal. It does not only improve the energy efficiency, increases the safety of production equipment, reduces the maintenance cost, but also provides a clean and safe working environment.
1. Double seal design (bellows + packing). If the bellows fails, the stem packing will avoid leakage.
2. Reasonable structure, reliable sealing, excellent performance and beautiful appearance.
3. No fluid loss. It can reduce energy losses and improve the safety of plant equipment.
4. The sealing surface is overlaid with Co based cemented carbide, which has good wear resistance, anti-corrosion, friction resistance, long service life, reducing maintenance times and operating costs.
5. Strong and durable bellows seal design ensures zero leakage of the valve stem and provides free maintenance.
6. The valve stem has good anti-corrosion and friction resistance by quenching and tempering, and surface nitriding treatment.
7. The indication of the valve stem lifting position is more intuitive.
