A shunt valve assembly includes an electromechanical brake mechanism that locks a position of a pressure setting mechanism within a shunt valve assembly. The electromechanical brake can maintain the position of the pressure setting mechanism in the presence of a relatively strong magnetic field to maintain a set pressure differential within the shunt valve assembly. In certain cases, the shunt valve requires repositioning of the pressure setting mechanism within the shunt valve assembly to adjust a fluid flow rate through the shunt valve assembly. A clinician can activate an external controller to transmit a signal to the shunt valve assembly through magnetically coupled antennas between the controller and the shunt valve. The shunt valve assembly utilizes the signal to activate the braking mechanism and unlock the pressure setting mechanism. The clinician then operates the controller to non-invasively reposition the pressure setting mechanism and adjust the pressure at which the shunt valve opens.
