JW41H German standard Flange stop valve

JW41H German standard Flange stop valve

Product working principle and use:

The product structure is reasonable and the seal is reliable. The flange valve is suitable for inflammable, explosive, highly toxic, toxic fluid, high temperature thermal oil, liquid ammonia, ethylene glycol and other industrial fluid media with nominal pressure PN16 ~ PN160 and working temperature -29 ~ 350℃. Destandard globe valve is used in petrochemical industry, chemical fiber textile, plastic paper making, electric power, steel, printing and dyeing rubber, natural gas and other gas systems, with safe and reliable performance.

Product structure features:

Dual robust bellows seal design (bellows + packing) ensures zero leakage of the valve stem. No fluid loss, improved plant equipment safety and compliance with international sealing standards.
German standard globe valve sealing surface surfacing Co based carbide, wear resistance, corrosion resistance, good anti-friction performance, long service life.
Valve stem tempering and surface nitriding treatment have good anti-corrosion and anti-friction properties; Valve stem lifting position indication, more intuitive.
