Operation Deep Reduction Air System (with A-6915 Roadranger Valve) In addition to the range air system components, the deep reduction air system uses a reduction cylinder and the Roadranger Valve A-6915. When the A-6915 Roadranger Valve is used, the deep reduction cover must be equipped with an insert valve. Air is supplied to the system at the air supply port (1) by the vehicle's air system. The air filter (2) removes foreign matter from the air and allows it to pass through the air regulator (3) where the pressure is adjusted for 58 to 63 PSI. From there, the air passes through the supply air hose (4) to the slave valve supply port (5) through the supply air line to the Roadranger valve (6). Depending upon the position of the Roadranger valve button (7), if air passes through the air line (8) connected to the reduction cylinder center port (9), then the deep reduction gearing is engaged. If there is no air, the constant air from the air filter/regulator assembly (10) moves the reduction piston rearward to disengage deep reduction gearing.
