This air compressor auxiliary valve works as a constant speed control device, and fits models 15T & H15T two-stage industrial air compressors. Compressors that utilize the 32170771 constant run valve have an internal centrifugal unloader that automatically bleeds the air from intercoolers and cylinders, preventing the compressor from starting against full load. This protects the motor from premature wear.
