Cast steel bellows disconnecting valve with bellows seal design, completely eliminated the ordinary valve stem packing seal aging fast easy to leak the shortcomings, not only improve the use of energy efficiency, increase the safety of production equipment, reduce maintenance costs and frequent maintenance, but also to provide a clean and safe working environment.
Product Features
- The product has reasonable structure and reliable sealing. Double rugged bellows seal design (bellows + packing) ensures that there is no leakage from the valve stem and no fluid loss.
- Seal surface surfacing Co-based hard alloy, wear-resistant, corrosion-resistant, good anti-friction performance, long service life.
- Valve stem tempering and surface nitriding treatment, has good anti-corrosion and anti-friction performance; stem lifting position indication, more intuitive.
