How the A6913 Roadranger Valve Works

Low Range Operation

Constant air pressure is supplied from the slave valve to the Roadranger valve “S” port (1). For LO range (range lever down), splitter button rearward, air flows out of the Roadranger valve “P” port.

High Range Operation

For HI range (range lever up), splitter button rearward, the lever prevents the air from passing through the Roadranger valve. Air now flows through the “H/L” port into the Roadranger valve.

Splitter Operation (High Range)

For splitter operation (range lever up), splitter button forward, air flows through the “H/L” port and air flows out of the Roadranger valve “SP” port. Air pressure which was in the outlet line is exhausted out the bottom of the Roadranger valve.

HI Range Overdrive

For HI range overdrive (range lever up), actuator button forward, air flows out of the Roadranger valve “SP” port. Air pressure which was in the outlet line is exhausted out the Roadranger valve bottom.
