303.15.0002 Compatible Check Valve — Volvo & Renault

What does a check valve do?

This check valve is a critical component within the pneumatic brake system of heavy commercial vehicles, ensuring that air flows in only one direction. By preventing backflow, it maintains system pressure and provides essential safety by isolating circuits during a pressure drop. This component is manufactured using heavy-duty grade materials to withstand rigorous operational demands.

Compatible vehicles and engines

The part is compatible with Volvo models including FH, FM, FMX, and VNL series, as well as Renault Trucks models like Kerax and Premium. It is also fitted to Mack Granite and Pinnacle trucks. This component is engineered to meet the requirements of Mercedes-Benz and Scania vehicles as well.

Installation and maintenance

For reliable performance, technicians should inspect the M16x1.5 ports for any signs of debris or wear during installation. Regular maintenance of the pneumatic circuit ensures that the 10 BAR operating pressure remains stable across all connected lines. Always consult your authorized distributor to ensure correct fitment.

System safety benefits

Proper selection of this check valve prevents system-wide pressure loss in the event of a single-circuit failure, maintaining braking integrity for the entire vehicle.
