Publication number: 20240247730Abstract: A stem controlled valve uses a stack which includes a plurality of spacing discs and a plurality of sealing discs, where the spacing discs are interdigitated between the sealing discs, or uses a monolithic plug or inner wall of a valve seat with spaced apart extension areas. The sealing discs or extension areas are slightly larger in diameter than a valve seat they fit within or plug wall they fit against such that they elastically deform against the inner wall of the valve seat or the outer wall of the plug. For sealing in cryogenic applications, at least the outer portions of the sealing discs, or the extension areas in the case of a monolithic plug and inner seat wall are pre-stressed to generate void spaces that govern deformation and cryogenic pliability of the single or groups of sealing discs.Type: ApplicationFiled: January 19, 2024Publication date: July 25, 2024Inventors: Jacob W.

Publication number: 20240247731Abstract: 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.Type: ApplicationFiled: April 2, 2024Publication date: July 25, 2024Applicant: MagDrive Technologies, Inc.Inventors: David Yakos, Stephen Sanford, Robert K.
