The 2 position or 2 way Solenoid Valves are normally closed, direct acting solenoid valves and do not require a minimum differential pressure to operate. As shown in the diagram below, when the coil is de-energized (left diagram), the plunger rests on the main orifice and is held in place by the plunger spring force, sealing the valve. When the coil is energized (right Diagram), magnetventilen løfter stemplet og giver arbejdsmediet mulighed for at strømme gennem åbningen . Arbejdsmediet og flowretningen er angivet i lilla i diagrammet .
