Stainless Steel Flanged Globe Valve J41W-25P DN50
The oxygen specific shut-off valve is made of high-quality silicon brass or stainless steel casting, which has the advantages of high mechanical strength, wear resistance, and good safety. Used on oxygen pipelines, it has effective explosion-proof and flame-retardant properties, eliminating unsafe factors on oxygen pipelines.

Details
The closing member of the national standard stainless steel globe valve is a cylindrical disc with either a flat or conical sealing surface, moving linearly along the fluid’s central axis. The national standard globe valve is designed strictly for fully open or fully closed positions and is generally not used for flow regulation—though custom-made versions may accommodate adjustment and throttling functions.
[Product Features]
1. Simple structure, making manufacturing and maintenance relatively convenient.
2. Short working stroke and quick opening/closing time
3. Excellent sealing performance, with low friction between sealing surfaces and a long service life.
