Abstract

A rotor is provided for use in combination with a valve 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 sleeve, and a rotor stem with ports to coact with complementary ports in the sleeve to form variable orifices to control fluid flow, and a flexible means for connecting the rotor stem to the rotor body.
