Stainless steel bellows shut-off valveThe bellows seal design completely eliminates the shortcomings of ordinary valve stem packing seal aging fast and easy to leak, not only improves the use of 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
- 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.
