1. A shunt valve assembly comprising:

  • a housing having an inlet port and an outlet port, the housing configured to carry a fluid between the inlet port and the outlet port;

    a valve coupled to the housing and in fluid communication with the inlet port and the outlet port, the valve having a pressure setting mechanism configured to adjust a pressure at which the valve will release fluid from the inlet port to the outlet port;

    an electromechanical brake assembly having a brake member disposed in proximity to the pressure setting mechanism; and

    a signal receiver in electrical communication with the electromechanical brake assembly, the signal receiver configured to receive an activation signal and transmit a positioning signal to the electromechanical brake assembly, in response to receiving the activation signal, to;

    (i) position the brake member in a first position relative to the pressure setting mechanism when the activation signal has a first value, and(ii) position the brake member in a second position relative to the pressure setting mechanism when the activation signal has a second value.
