DESCRIPTION

The TLV-9000

 lift axle valve is used on trailers or 

vehicles with Bendix

®

 TABS-6

 Advanced single- and 

multi-channel systems to control the lift axle(s) raising 

and lowering automatically.  This allows the vehicle to 

use extra axle(s) when required for payload distribution 

and to be unloaded to save on wheel-end wear and fuel 

economy.
