If there is a uniform rule throughout the factory, is it better for solenoid valves to operate at 220V or 24V?
Thread Content
As titled, the electrical system indicates 220, but the meter shows 24
Considering factors such as safety, stability, and maintenance costs, it is recommended to choose 24V.

There is a uniform specification for the voltage of solenoid valves throughout the plant – what a terrible idea! The conditions in various processes across the entire plant vary (valve diameter, location, explosion protection rating, power requirements and conditions, electromagnetic environment, temperature, etc.). How can there be unified regulations in such a situation? ?
Only some seemingly smart idiots in the factory would come up with such stupid ideas and rules
Why is there a need for uniform regulations? Are you trying to unify the six states?
Classify them: the solenoid valves on shut-off valves definitely require a low-power 24V supply. Large-diameter electric valves, on the other hand, usually have motors for driving them, so a 220V supply is necessary. It’s possible that what electrical instruments refer to is not the same thing
Using 24V is safer when the power level is not high
This was also suggested by some designers; it’s actually meant to save time. But since the idea has been raised, it would be good to have at least some suggestion or a principle-based guideline, otherwise it will indeed cause trouble
The forum is a platform for everyone to communicate; there’s no need to belittle others.
I have only seen one case where 220V is used to account for the issue of long distances, or where a 24V low-power solenoid valve is employed.
