1. Which manufacturers’ oxygen flow control valves are most commonly used? What is their performance? What are the typical pressure differences before and after the valve, as well as the valve position?
What do the numbers before your question mean? There is a number in front of each of your posts
There are still differences between different grades, right? The valve position itself affects the pressure difference, and changes in the oxygen pressure in the air separation unit as well as the operating pressure of the gasification furnace also have an impact on the valve position and the pressure difference
Oxygen control valves from Masoneilan, Flowserve, and Fisher are all suitable options; currently, there are also large domestic manufacturers producing such valves, such as Kaivixi and Chauda. The pressure difference before and after the valve, as well as the valve position, vary depending on the device.
