Dear masters, may I ask whether the high-dilution valve is a wind-open valve or a wind-close valve?

It’s not clear whether the high-doping valve in the device is a wind-on valve or a wind-off valve; what type do you experts think it should be?
The selection principle for wind-on valves and wind-off valves is to ensure safety in emergency situations.
The high-temperature mixing valve is double-acting; the cylinder piston is surrounded by instrument air on both the upper and lower sides, and there are no springs – as a result, the valve remains in its original position when the air supply is stopped.
Master, is there any evidence for this? Or do valves with a high concentration of such elements inherently possess these characteristics?
I can’t answer your question that way; the choice between air-on and air-off modes is determined from the perspective of process safety. The applications for high-temperature mixing valves vary, and therefore the selection between air-on and air-off modes also differs.
