Beschreibung
Zusammenfassung:	The present invention is directed to an electromagnetic actuation system for opening and closing pipe valves. The electromagnetic actuation systems utilizes one or more electromagnets surrounding one or more permanent magnets attached to a rotary shaft of the valve mechanism. A controller activates the one or more electromagnets such that the produced magnetic field rotates, thereby applying a force to the one or more permanent magnets and thus rotating the rotary shaft. The system does not require rotation of the one or more electromagnets relative to the one or more permanent magnets, advantageously reducing the number of moving parts within the valve system.
