WCB Natural Fuel Gas Bellows Globe Valve

Product Introduction

  KWJ41F-16C gas bellows globe valve is manufactured with advanced metal bellows sealing technology. The product uses a bellows seal design, which eliminates the shortcomings of rapid aging and easy leakage of ordinary valve stem packing seals, which not only improves energy efficiency,  increases the safety of production equipment, reduces maintenance costs and frequent maintenance, but also provide a clean and safe working environment. This product is widely used in petrochemical industry, chemical fiber textile, papermaking, electric power steel, printing and dyeing rubber, food and other industries. KMO's products have reliable quality, reasonable price and perfect after-sales service.

Features of Product

1. Simple structure and convenient maintenance.

2. Short working time and quickly open & closing.

3. The sealing surface is surfacing with Co-based hard alloy, which is wear-resistant, corrosion-resistant, good in friction resistance, long service life, reduces maintenance and reduces costs.

4. During the opening & closing, the friction of the sealing surface is smaller than that of the gate valve, and it is wear-resistant.

5. It is usually only one sealing surface, good process.

6. Double seal design (bellows + packing). If the bellows fails to seal, the stem packing will be avoided.

7. Reasonable structure, reliable sealing, excellent performance and beautiful appearance.

8. No fluid loss, which reduces energy loss and improves plant equipment safety.

9. The sturdy and durable bellows seal design ensures zero leakage of the valve stem and provides maintenance-free conditions.

10. The stem of the globe valve is quenched and tempered and surface nitriding treatment, with good corrosion resistance and friction resistance.

11. The valve stem lifting position indication is more intuitive.
