2 Way Solenoid Valve is used in fluid power pneumatic and hydraulic systems, to control cylinders, fluid power motors or larger industrial valves. This is used to close, open, dose, distribute or mix the flow of gas or liquid in a pipe. The specific purpose of this valve is expressed by its circuit function. 2 Way Solenoid Valve has 2 pipe connections, an inlet called the cavity port and an outlet called the body orifice port. When the valve is energized the plunger opens allowing media to flow through the valve in the cavity port and out the body orifice port. The orifice closes and flow through the valve stops.
