First, the bellows globe valve Product Overview  
 J41H bellows globe valve is my company to introduce advanced German technology, the use of advanced metal bellows seal manufacturing technology, high-performance metal bellows, bellows seal globe valve bellows seal design, complete Eliminating the shortcomings of common valve stem packing aging fast leakage, not only improve the use of energy efficiency, increase the safety of production equipment, reduce maintenance costs and frequent maintenance, but also provide a clean and safe working environment. Bellows globe valve is widely used in petrochemical, chemical fiber textile, plastic paper, power steel, printing and dyeing rubber, food and other industries. 
 J41H / W type PN16 ~ PN40 bellows globe valve for working pressure 1.6 ~ 4.0MPa, operating temperature -29 ~ 350 ℃ oil, chemical, pharmaceutical, fertilizer, power industry and other conditions, but the break or access Adjust the pipe media.
 

Second, the bellows globe valve features  
 1, the product structure is reasonable, reliable sealing, dual rugged bellows seal design (bellows + packing) to ensure zero stem leakage. No fluid loss, reduced energy loss and increased plant safety. And in line with international standards of sealing. 
 2, the sealing surface surfacing Co-based carbide, wear-resistant, corrosion-resistant, good anti-friction performance, long service life 
 3, the valve stem quenching and surface nitriding treatment, good corrosion and friction performance; stem Lift position indication, more intuitive.
