What is a SmartValve?

SmartValve is an electronic height control valve for the suspension. The SmartValve allows the suspension to go into an over-height position when wheel speed is under 10 mph to reduce effort needed in trailer coupling operation.

What happens when the driver leaves the SmartValve in Over Height Mode?

The SmartValve monitors the wheel speed signal and will automatically return to standard ride height when the vehicle speed exceeds 7-10mph. An additional feature of the SmartValve is it will automatically raise the suspension if the dump switch is left on and the tractor exceeds 17mph.

Will the SmartValve work on my truck?

Possibly; SmartValve is available for every make of tractor. However, the SmartValve does requires the J1939 CanBus signal. The SmartValve will not allow the vehicle to enter over-height mode without this signal. J1939 signal is found on most tractors 2006 and newer. Your local dealership should be able to let you know if your vehicle has this signal from the VIN.

How does the SmartValve work?

The SmartValve operates with the same function as a mechanical height control valve while the vehicle is driving down the road. Retrofit kits typically use the existing suspension dump switch to lower the suspension and add a single momentary push button to allow over inflation.

How long is the warranty for a SmartValve?

The SmartValve offers an unprecedented 3 year warranty on parts along with a 1 year warranty for labor.

How long does it take to install a SmartValve?

Typically takes between 2-3 hours to install a SmartValve kit. As with any other retrofit kit, the 1st time can take a little longer.

What happens if there is a failure with the SmartValve?

The SmartValve uses an interface module to monitor the system for faults. In the event of a failure the LED will blink a green pattern to alert the driver of a malfunction.

If communication is interrupted between the SmartValve and the Module the LED will blink red. This is to alert the driver the SmartValve is no longer communicating and the SmartValve will remain in the position where the failure occurred. Please email service@hadleyadvantage.com with any questions.

Does the SmartValve lower the suspension at highway speeds?

No, the SmartValve will maintain vehicle ride height while driving at highway speeds.

How high is the SmartValve able to raise the suspension?

The SmartValve is limited by the travel of the shock absorbers. Average vehicle will be able to raise the 5th wheel 1.5”-2.5”
