description A control valve assembly for use in a wellbore includes a body having a fluid inlet and a fluid outlet. A portion of the body is formed from magnetic material. A plunger is mounted within the body. A portion of the plunger is formed from a magnetic material. A magnetic circuit having a gap is defined within the control valve assembly. The portion of the body formed from magnetic material defines a first portion of the magnetic circuit and the portion of the plunger formed from magnetic material forms another portion of the magnetic circuit. A solenoid is mounted at the body. The solenoid is selectively activated to create a magnetic field across the gap in the magnetic circuit. The magnetic field causes the plunger to shift, narrowing the gap disengaging from the one of the fluid inlet and the fluid outlet to produce a pressure pulse in the wellbore.
