Abstract: A downhole valve apparatus includes: a force transmitter configured to move in an axial direction; a valve actuator configured to move in an axial direction, the valve actuator independently movable relative to the force transmitter and physically isolated from the force transmitter; a first magnetic assembly disposed at the force transmitter; and a second magnetic assembly disposed at the valve actuator, the first and second magnetic assemblies configured to repel one another and cause the force transmitter to move the valve actuator when the force transmitter is moved toward the valve actuator.

Abstract: The problem of flappers that will not close due to high velocity gas rushing past and creating a vortex that has zones of high pressure pressing the flapper against the force of the torsion spring is reduced or overcome with modifications in the passage through a subsurface safety valve so as to reduce the intensity of the vortex to allow the torsion spring to pivot the flapper to closed position. Various shapes are inserted adjacent the flapper base to create turbulence to minimize or prevent the vortex and the associated pressure increases that would otherwise prevent flapper closure with the flow tube retracted. Inserts that create turbulence are placed in a recess that in part holds the flapper when it is rotated to the open position.
