Oxygen Gate Valve

ZY41H Stainless Steel Oxygen Gate Valve Oil-prohibited Z41W Stainless Steel American Standard Gate Valve is suitable for use in the pipeline of various systems in petroleum, chemical, hydraulic and thermal power stations to cut off or connect the pipeline medium.

In recent years, with the increase of oxygen consumption, large oxygen users are using oxygen pipeline transportation. Due to the long pipeline, wide distribution, coupled with the rapid opening or quick closing of the valve, resulting in oxygen pipeline and valve combustion and explosion of the accident occurred from time to time, so a comprehensive analysis of the oxygen pipeline and the existence of the hidden dangers of the cold door, the danger, and to take appropriate measures is essential.

Oxygen gate valve, including valve body, valve stem and gate plate, valve seat and gate plate correspondingly fit, in the valve seat embedded PTFE valve seat ring, the PTFE valve seat ring protrudes from the surface of the valve seat, the corresponding part of the gate plate and PTFE valve seat ring contact sealing fit. The structure of this utility model is reasonable, in the process of valve opening and closing, the gate only and PTFE valve seat ring friction, there will be almost no fine metal powder off, not only eliminates the safety hazards, and the sealing vice of the wear and tear is small, reliable use, better airtight performance.
