HQ Norgren Series 5040″ is the Lift Axle Control Module

HQ is introducing Norgren’s 5040 Lift Axle Control Module. The 5040 series directly benefits the heavy-duty truck and trailer industry. The Norgren engineered unit is built with a cast aluminum body for durability. Plus, it includes thermoplastic pistons and low-temperature nitrile seals. This combination does resist contamination and temperature extremes, unlike many commonly used spool valves.

You can count on this innovative, chassis-mounted module that integrates two industry-proven, brake-style relay valves into a single compact unit. It delivers excellent flow capability for rapid axle actuation.

For versatility, the HQ Norgren 5040 series comes in three variations; electrical or air-pilot-operated versions,

You can mount the 5040 directly on the transmission for ease of installation. Instruction PDF is linked below.
