54341 Series


The 54341 Series relies on negative air pressure
to actuate the dump feature. This feature allows
the seamless integration of the reverse dump
valve into the trailer parking brake system.
When parking brakes are set, the negative
pressure that allows the brakes to lock will also
allow the dump feature to be actuated. The
negative air pressure allows the dump valve to
return to its "normally open" state and exhaust
the trailer air suspension.



  • Shear-Seal® technology provides superior peformance and durability
  • Automatically exhaust trailer air springs when parking brake system is engaged
  • High-flow design for rapid fill and exhaust
  • Integrated dump feature reduces installation parts and costs while minimizing leakage points
