1、 Product Overview:
The bellows sealed globe valve is a high-performance metal bellows valve manufactured by the company using advanced German technology and advanced metal bellows sealing technology. The bellows sealed globe valve adopts a bellows sealed design, completely eliminating the disadvantages of aging and leakage of ordinary valve stem packing seals. It not only improves energy efficiency, increases production equipment safety, reduces maintenance costs and frequent maintenance, but also provides a clean and safe working environment. Widely used in industries such as petrochemicals, chemical fiber textiles, plastic papermaking, power steel, printing and dyeing rubber, food, etc.
2、 Structural features:
1. The product structure is reasonable, the sealing is reliable, and the double sturdy and durable corrugated pipe sealing design (corrugated pipe+packing) ensures zero leakage of the valve stem. No fluid loss, improving factory equipment safety. And comply with international sealing standards.
2. Sealing surface welding with Co based hard alloy, wear-resistant, corrosion-resistant, good friction resistance, and long service life
3. The valve stem undergoes quenching and surface nitriding treatment, exhibiting excellent corrosion resistance and friction resistance; Valve stem lifting position indication, more intuitive
