Abstract
A thermal control valve for use in a lubricant flooded compressor system including a controller that generates a control signal includes a valve body including a hot coolant inlet, a cooled coolant inlet, a mixed coolant outlet, an actuator space, and a cylinder bore. A sleeve is positioned within the cylinder bore and is movable between a first position, a second position, and a third position, and an electrical actuator is at least partially disposed within the actuator space and is operable in response to the control signal to move the sleeve between the first position, the second position, and the third position.
