Abstract
A control valve assembly includes a body having a fluid inlet and a fluid outlet. A portion of the body is formed from a first magnetic material. A sleeve is slidingly mounted to the body. At least a portion of the sleeve is formed from a second magnetic material. A magnetic circuit having a gap is defined within the control valve assembly. A solenoid is mounted to the body about at least a portion of the first magnetic material of the body. The solenoid is selectively activated to create a magnetic field across the gap in the magnetic circuit. The magnetic circuit causes the sleeve to slide, narrowing the gap and sliding from the first position to the second position to produce a pressure pulse in the wellbore, wherein the biasing member biases the sleeve back to the first position.
