Below is a list of 3 Way Solenoid Valves manufacturers from South Bend, Indiana. A 3 way solenoid valve is a type of flow control valve that has three connections and two orifices. Most 3 way solenoid valves are manufactured for air and gas flow regulation, which results in mostly pneumatic valves; however, hydraulic 3 ways solenoid valves are also available. Three way solenoid valves are powered by natural pressure and electromagnetic force; having fewer moving parts is considered good design, since moving parts require maintenance. 3-way solenoid valves are also easily operated by remote devices that activate the solenoid coil, making 3 way solenoid valves extremely useful for operating potentially dangerous machinery or inaccessible lines.
