FAQ
How can I ensure this repair kit fits my valve?
To ensure correct fitment, check the manufacturer's part number on the existing valve housing and verify it matches your vehicle's model and engine specifications.
Which vehicle brands are compatible with this kit?
This kit is compatible with Volvo trucks (including F12 and FL10 series) and is also used in DAF, Iveco, and Mercedes-Benz heavy commercial vehicles.
What is the benefit of using a repair kit instead of a new valve?
A repair kit allows for an economical restoration of the valve's internal seals and spring calibration, returning it to factory performance without replacing the entire unit.
What are common symptoms of a faulty protection valve?
Technicians should look for pressure drops in specific circuits or air leaks that prevent the system from maintaining balanced pressure across all four independent circuits.
What are the OE reference numbers of this part?
303.02.0013.01 directly replaces Knorr-Bremse OE number I80448.
