A valve including a housing having a coil therein; a seat in the housing; a ball disposed against the seat, the ball rotationally responsive to a magnetic field generated in the coil.

First claim

Opening claim text (preview).

What is claimed is: 1 . A valve comprising: a housing having a coil therein; a seat in the housing; a ball disposed against the seat, the ball rotationally responsive to a magnetic field generated in the coil. 2 . The valve as claimed in claim 1 further including a first permanent magnet disposed at the ball. 3 . The valve as claimed in claim 2 wherein the magnet is an integral part of the ball. 4 . The valve as claimed in claim 2 wherein the magnet is separate from the ball. 5 . The valve as claimed in claim 4 wherein the magnet is attached in a recess of the ball. 6 . The valve as claimed in claim 1 further comprising an automatic closure arrangement. 7 . The valve as claimed in claim 6 wherein the automatic closure arrangement is a resilient member. 8 . The valve as claimed in claim 7 wherein the resilient member is a torsion spring. 9 . The valve as claimed in claim 2 further comprising a second permanent magnet magnetically opposing the first permanent magnet. 10 . The valve as claimed in claim 6 further including a first permanent magnet disposed at the ball and wherein the automatic closure arrangement includes both a resilient member and a second permanent magnet urging the ball to a closed position. 11 . A wellbore production system comprising: a tubing string disposed in a borehole of a subsurface formation; and a valve as claimed in claim 1 disposed in the tubing string.
