Electromagnetic actuator

摘要

The actuator has an armature plate(1) with an integral pin (4) that is in contact via a disc (61) with the valve stem (5). Electromagnets (2,3) are on both sides of the armature plate and generate opening and closing forces. The actuator and valve assembly have coil spring elements (60,63) The surface of the armature disc is coated with a wear resistant chrome- nitride layer (9).
