ABSTRACT:
An alternating electric current integral pilot valve actuator and pilot valve. The magnetic flux core of the actuator is a short flux path through a "U" shaped magnetic material piece providing two pole pieces for a magnetic material valve member to be pulled against the two pole pieces which then completes the magnetic flux path, opens an integral pilot valve port and reduces the coil current to a lower level.
