Abstract

An electromagnetic rising stem valve includes a stopper configured to block flow of fluid within a pipe. The stopper is connected to a shaft configured to be rotated via an electromagnetic force generated between magnets attached to the outside of the shaft and magnets surrounding an outside surface of a section of the valve. The rising stem valve is further able to include a second shaft which is directly rotated by the electromagnetic force, to open, closed, and one or more semi-open positions, and which is coupled to the shaft connected to the stopper via gearing. Advantageously, the one or more shafts and any gearing is entirely contained within a gear housing, with the electromagnetic force being generated by interaction with magnets outside the housing entirely, preventing unwanted leakage of fluid from the pipe into the environment.
