  • Position detection for rotary control valves
    Patent number: 6484751
    Abstract: A rotary control valve includes a flow control element having a lower valve shaft rotatably received in a non-magnetic body portion. A magnet is coupled with a lower valve shaft and rotatable therewith to produce an external magnetic field that varies in accordance with the angular position of the flow control element. A magnetic field detector, positioned in the external magnetic field, is operable to detect the external magnetic field and to produce position signals representative thereof, such being indicative of the angular position of the flow control element.
