What are Bellow Seal Globe Valves

The bellows seal globe valve adopts the design of bellows seal, which completely eliminates the shortcomings of rapid aging and easy leakage of ordinary valve stem packing. It not only improves the use of energy efficiency, increases the safety of production equipment, reduces the maintenance cost and frequent maintenance, but also provides a clean and safe working environment.

Structural characteristics of bellows seal globe valve

  • 1. Double sealing design (bellows + packing) if the bellows fails, the valve stem packing will also be avoided.
  • 2. Reasonable structure, reliable sealing, excellent performance and beautiful appearance.
  • 3. No fluid loss, reduce energy loss and improve plant equipment safety.
  • 4. The sealing surface is overlaid with Co based cemented carbide, with good wear resistance, corrosion resistance, friction resistance and long service life, so as to reduce the number of maintenance and reduce the operating cost.
  • 5. The rugged bellows sealing design ensures zero leakage of the valve rod and provides conditions without maintenance.
  • 6. The globe valve stem is subject to quenching and tempering and surface nitriding treatment, with good corrosion and friction resistance;
  • 7. The valve rod lifting position indication is more intuitive.
