First, the product overview:
Bellows sealed globe valve is the introduction of advanced German technology company, the use of advanced metal bellows sealing technology, high-performance metal bellows, bellows seal globe valve bellows seal design to completely eliminate the common valve stem packing seal aging The shortcomings of quick leaks not only improve energy efficiency, increase the safety of production equipment, reduce maintenance costs and frequent maintenance, but also provide a clean and safe working environment. Widely used in: petrochemical, chemical fiber textile, plastic paper, power steel, printing and dyeing rubber, food and other industries.
Second, the structural features:
1, the product structure is reasonable, reliable seal, dual rugged bellows seal design (bellows + filler), to ensure zero stem leakage. No fluid loss, improve factory equipment safety. And in line with international standards of sealing.
2, the sealing surface surfacing Co-based cemented carbide, wear-resistant, corrosion-resistant, good anti-friction performance, long service life
3, the valve stem quenching and nitriding treatment, good corrosion and friction performance; stem Lift position indication, more intuitive
