API bellows globe valve

The release date:[2017-08-07]     hits

First, the American standard bellows valve Overview:
American standard bellows valve with bellows seal design, completely eliminate the common valve stem packing seal aging easy to leak shortcomings, not only improve the use of energy efficiency, increase production safety , Which reduces the maintenance costs and frequent maintenance, but also provides a clean and safe working environment; for the nominal pressure PN1.6 ~ 16MPa, operating temperature -29 ~ 350 ℃ of oil, chemical, pharmaceutical, fertilizer, power and other industries The
Second, the American Standard bellows valve advantages:
(1) a dual seal design (bellows + fill) if the bellows fails, the stem packing will prevent leaks, and sealed in accordance with international standards
(2) no fluid loss, reduce energy loss and improve plant safety equipment
(3) long service life, reduce maintenance times and lower operating costs
(4) rugged bellows seal design to ensure zero leakage of the valve stem, provide conditions for maintenance-free
(5) gas medium seat The use of PTFE soft seal material to improve the valve seal
(6) high temperature ≤ 425 ℃ seat with a hard seal. Reaches zero leakage tightness
(7) and technical performance of all products according to German standard ARI Standard manufacturing
three, American Standard bellows valve structural characteristics :
(1) reasonable structure, reliable sealing
(2) Co-based hard surfacing sealing surface carbide, wear, corrosion, good anti-friction properties, long life
(3) stem quenched and surface nitriding treatment, good corrosion and friction resistance
(4) and flange part material, welding end according to the actual size of the working conditions or the user 'requirement, to meet the needs of various engineering
(5) bearing the valve body can be cut as desired and modulating type
