Electric valve for circulating water
Thread Content
Do electric valves used for circulating water require a fire protection rating of API607 as well as anti-static properties?
It can be adjusted according to your specific situation!
In non-explosion-proof areas where there are no flammable materials either, what do you usually do?
No need; in a circulating water safety zone, fire and static electricity protection is not necessary

In some cases, water used for extinguishing fires is not effective either—calcium carbide (as mentioned in yesterday’s Focus Interview)
Why are fire protection requirements necessary in non-explosion-proof areas? It is a non-explosive area without flammable materials, making it a safe zone. As for anti-static measures, I think they are excessive, as both the pump and the motor itself require to be grounded. This question is best answered by electrical professionals.
Well, I have a question that isn’t related to this post – are all recirculation water plants non-explosion-proof? Does any of your departments have information on this?
In a circulating water plant, the cooling tower area is generally an explosion-proof zone. The classification of explosion-proof areas falls within the scope of the electrical engineering field.
Take a look at how your factory divides its areas! !
