Abstract
A valve that includes a wall, a closure member, a motive force device, a coupling member, and a sensor. The wall defines a flow passage that is disposed along a longitudinal axis. The closure member is disposed in the flow passage and is rotatable on a first axis that is oblique to the longitudinal axis. The closure member is rotatable between a first position that substantially prevents flow through the flow passage and a second position that generally permits flow through the flow passage. The motive force device rotates the closure member between the first position and the second position. The device includes a rotor that is rotatable with the closure and includes a stator that is disposed proximate to the rotor. The coupling member conveys motive force of the device to rotation of the closure member. And the sensor detects the angular position of the rotor with respect to the stator.
