Abstract
A rotor is provided for use in combination with a stator and sleeve to function as a valve attached to an actuator. The rotor is comprised of a rotor body containing the drive section with the necessary elements to turn the rotor within the stator and sleeve, and a rotor stem with parts to act with complementary parts on the sleeve to form variable orifices that function as the valve. The rotor body is connected to the rotor stem by a flexible joint which includes a contoured surface to compensate for misalignments in the system.
