Abstract
A downhole valve apparatus including a force transmitter configured to move in an axial direction and a valve actuator configured to move in an axial direction. The valve actuator is independently movable relative to the force transmitter and physically isolated from the force transmitter. A first magnetic assembly is disposed at the force transmitter. A second magnetic assembly is disposed at the valve actuator. The first and second magnetic assemblies are 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.
