Can electric butterfly valves with DN200 and DN300 diameters be fully opened in 1 second?
Thread Content
Can electric butterfly valves with DN200 and DN300 diameters open completely in 1 second, remain in that state for a few seconds, then close in 1 second, repeating this cycle? The operating temperature is very low, around minus 30 degrees. I need an answer online right away; it’s urgent!
I’ve never heard of anyone whose home installation work is good; your profile picture shows a pneumatic valve – why not consider using pneumatic systems?
Generally, electric actuators are rarely required to have a specific switching time; I’ve never seen such a requirement. My boss said the fastest time observed is around 3 seconds, while one second is quite difficult to achieve. It is recommended to consider improving the pneumatic system; the 4 sequence valves used in the polypropylene workshop before were all pneumatic, with their switching times being within one second.
Okay, thank you. I’ll talk to the client again
You’re welcome. I hope someone expert can solve your problem, and it will also help me learn a lot.
The normally open, power-off shutdown can be accomplished within 1 second. However, it probably won’t work if the device is powered on for just 1 second before attempting to open; at the very least, the electromagnetic force isn’t generated instantaneously. Usually, pneumatic is faster; for quick on/off operations, pneumatic is the best choice. If it’s just for turning off, electric is better. (Personal opinion)
I have a headache too; with such a large diameter, the gears can’t rotate that fast, and the switching and stopping actions still need to be repeated in cycles
Won’t the electric valve freeze in outdoor temperatures of minus 30 degrees?
No, this temperature isn’t a challenge; many people can handle it
I was wondering if there is grease inside, and whether it can freeze
Temperature isn’t the challenge; the problem is that it cannot be achieved using electricity. It seems that some manufacturers can achieve it through electro-hydraulic control
