System Components Range Actuator Valve (Old Design) Constant air pressure is supplied from the air filter/regulator to the range actuator valve "S" port tee (1). For LO range (1, 2, 3, 4, 5, and 6 gear positions) the "S" port (2) is open and the air is allowed to pass through the range actuator valve and out the LO range air line (3).
For HI range (7, 8, 9, and 10 gear positions) the "S" port (2) is closed and no air passes through the range actuator valve (3).
