1. An electronic modulating valve for controlling a flow of refrigerant through a refrigerant system, the modulating valve comprising:
a valve body having an inlet passage and an outlet passage;
an electrically actuated valve member mounted in the valve body, the valve member being movable within the valve body to modulate flow of fluid between the inlet passage and the outlet passage;
an electric power element having at least a portion of an electric actuator;
an electronic controller operably connected to the electric actuator, the electric actuator being operably connected to the valve member to control movement of the valve member in response to commands from the electronic controller; and
a probe configured to sense a mechanical vibration in the refrigerant system;
wherein the electronic controller is operably coupled to the probe and is configured to receive information from the probe that corresponds with the mechanical vibration, the electronic controller being configured to control movement of the valve member via the electric actuator in response to the information received from the probe.
