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
