Questions regarding the air-on/air-off valves of control valves
Thread Content
At what pressure below the instrument air pressure will the air-operated control valve close? ?
It should shut off completely only when the pressure reaches zero; when the pressure drops to a certain level, only part of it will shut off, rather than everything shutting off.
The instrument air pressure is low; the valve closes gradually, and it will only close completely when the pressure reaches 0. The solution upstairs is correct. As for the specific pressure at which closing starts, it varies from valve to valve; you can refer to the air supply pressure indicated on the nameplate
It is a gradual process; the compressed air supply is interrupted, but the purification air tank still maintains a certain pressure
0.3MP3 should still work normally, right?
Each type of valve has different curves; for specific details, refer to the operating curve of that particular valve
At what pressure does it start to shut off? Each valve is different; it closes completely when there is no air pressure.
If the air supply is suddenly cut off while the valve is in use, it will gradually close. As for the pressure level at which closing begins, this varies depending on the design of each manufacturer
