Flanged Oxygen Globe Valve
The JY41W-40P is a stainless steel globe valve specifically designed for oxygen pipeline systems, with flanged ends and PN40 pressure rating. All internal surfaces are oil-free cleaned (degreased) to ensure safety in oxygen-enriched environments. The valve features a rising stem, bolted bonnet, and precision-machined sealing surfaces for reliable shut-off performance.
