Norgren 5040 Series - Manual

Features
This chassis-mounted lift axle control module,
specifically designed for the heavy duty truck and
trailer industry, provides full pneumatic control.
The module includes two industry-proven brake-
style relay valves integrated into a single unit for
compactness and ease of installation. The module
provides excellent flow capability for rapid axle
actuation and is available with an optional control
solenoid for electric control. More robust than
commonly used spool valves that can suffer from
contamination and temperature extremes.
