Used in past reliable 24 v NC 1/2” used in water filtration system on 24/7 no issues so far
Works well but tend to get really hot to point where can’t hold the metal part. Confirm using correct voltage on the valve . Purchased normally closed version. Probably much better when used with actual water as will cool the valve . Tested in test environment not connected to water
We have now used these valves and there are no issues of getting hot when used in water filter system
