Product advantages
On the basis of considering the operating characteristics of the oxygen pipeline network, the oxygen shut-off valve has the following advantages:
1. The oxygen stop valve is made of silicon brass or stainless steel with excellent Material, which has the advantages of high mechanical strength, wear resistance and good safety. Used on oxygen pipelines, it has the best explosion-proof and flame-retardant performance, eliminating unsafe factors on oxygen pipelines.
2. The sealing surface is made of stainless steel body processing or hard alloy welding, which is not easy to wear and scratch, has good sealing performance, and there is no relative sliding between the valve disc and the valve body sealing surface when opening and closing, so the wear and scratch are not serious, the sealing performance is good, and the service life is long.

3. For valves with PN ≤ 4.0MPa and DN ≤ 200, a single valve disc structure is adopted, and the medium flows from below the valve disc into above (i.e. low inlet and high outlet).
4. The bracket part adopts a fully enclosed structure, and the protective cover plate on the bracket can be opened when the packing is compressed, which plays a role in preventing oil and dust. And there are obvious oil prohibition signs.

5. The upper part of the valve stem is equipped with a dust-proof device. All valve parts in contact with oxygen are subject to strict degreasing and oil prohibition measures before assembly. The packing and gasket Material is polytetrafluoroethylene, which can ensure safe and reliable sealing during use.
6. The valve is equipped with a static electricity safety device to prevent sparks from being generated due to static electricity. There is a grounding screw on the valve body flange, which directly exports the static electricity of the valve through a wire to ensure the safety of valve use.
