Solenoid valves control the flow of liquid or gas media in all types of systems and products by allowing media flow when electrically energized or de-energized. These direct acting valves are used to shut off, release, dose, distribute or mix fluids or gasses and may have two or more ports to accomplish the task. Two-way solenoid valves have one inlet and one outlet port and a single orifice while three-way valves have three port connections and two valve orifices.
Do you need a 2-Way on/off or a multi-port (3 way) valve?
Is it normally closed or normally open?
Will the valve operate on short or long cycle times?
