Easy to operate | Electric valve | Affordable

Electric valves are generally divided into two types: normally closed and normally open. The normally closed type means that the valve is closed when the power is cut off. The normally open type means that the valve is open when the power is cut off. In addition, the wiring is divided into three-wire and two-wire systems, with large diameters. Most of them are three-wire systems, and there are two-wire and three-wire systems for small-caliber ones.
