1. A valve comprising:

  • a conduit comprising an inlet and an outlet, the conduit configured to receive a fluid via the inlet and discharge the fluid from the outlet after the fluid passes through the conduit;

    a motor comprising a stator and a magnetic rotor, the magnetic rotor disposed to contact the fluid as the fluid passes through the conduit and being positioned with a rotor axis of rotation substantially aligned with a direction of fluid flow through the conduit, the stator disposed to at least partially encircle the magnetic rotor and to cause rotation of the magnetic rotor around the rotor axis of rotation in response to electrical power provided to the motor; and

    a modulating orifice located between the inlet and outlet, the modulating orifice comprising a flow passage through which fluid can flow;

    a flow control element connected to the magnetic rotor such that the flow control element moves in response to rotation of the magnetic rotor, movement of the flow control element causing a size of the flow passage of the modulating orifice to change in a controllable manner.
