描述
YJ41W 氧气截止阀
The YJ41W oxygen globe valve is specially designed for oxygen pipeline systems.
It is mainly used to connect or isolate oxygen and is not normally used for flow
throttling. The valve is widely applied in oxygen service systems for steel
plants, metallurgy, petrochemical plants and chemical processing facilities.
The valve is manufactured under strict oil-free procedures. All components are
thoroughly degreased before assembly to prevent oil and grease contamination.
Conductive threaded holes are provided on the flanged ends of the valve to help
prevent static electricity. Exposed parts are protected against dust and oil
contamination during storage, installation and operation.
The YJ41W oxygen globe valve is available with cast silicon-brass or high-quality
stainless-steel body, bonnet and disc materials. It is suitable for oxygen
pipeline isolation under normal-temperature service.
