ABSTRACT:
A manually operable actuation pin for operatively engaging the solenoid armature of an electromagnetic valve device is provided to permit manual emergency or auxiliary control of the armature. The actuation pin is designed to permit locking in its actuated position by rotation thereof. The operating end of the actuation pin is arranged with an inner segment, an intermediate segment and an outer segment defined by annular grooves therebetween adapted to facilitate separation of the respective segments. One or more of these segments may be removed to obtain a specific operating characteristic in accordance with which the actuating pin is to be operated.
