Abstract
A continuous run controller for a dual control compressor system includes an integrated housing containing a pilot valve and a hydraulic unloader valve. Low pressure in the hydraulic oil system opens the hydraulic unloader valve such that the suction valve unloader assembly unloads the compressor. High pressure in an air receiver of the compressor system opens the pilot valve such that the suction valve unloader assembly unloads the compressor.
