Abstract
A valve comprises an electromagnetic actuator including a solenoid. The solenoid includes at least one core and an anchor plate. The solenoid further comprises at least one coil disposed within the core and connected to a set of power electronics to supply current to the coils. The actuator further comprises a plunger connected to the anchor plate and at least one spring configured to guide the plunger. The actuator also includes a pressure compensation system. The opening and closing of the valve is controlled by passing current through the coil.
