Abstract:
1. A solenoid actuator for a valve having a valve member movable within a housing to control the flow of a working media through an interior of the housing from an inlet port to an outlet port, the actuator comprising: a wire coil and at least one pole piece made of a magnetically active material; a solenoid retainer configured to couple to the housing and defining an interior space containing the wire coil and the at least one pole piece; a magnetically inert barrier member forming a closed end of the solenoid retainer; and a magnetically active armature separated from the wire coil and the at least one pole piece by the barrier member, the armature being configured to couple to the valve member to move the valve member when the wire coil is energized and de-energized to control communication between the inlet port and the outlet port; wherein, when the solenoid retainer is coupled to the housing, the solenoid retainer, the armature and the barrier member are in communication with the working media and the barrier member seals off the wire coil and the at least one pole piece from the working media.
