303.15.0001 Heavy-duty Check Valve compatible with Volvo and Renault Trucks

What does a check valve do?

A check valve is a critical safety component in the air brake system of heavy commercial vehicles, allowing air to pass in only one direction and preventing backflow. This part ensures that pressure remains stable within the braking circuit by preventing air loss from one circuit to another during a system failure.

Vehicle and engine compatibility

This component is specifically designed for use in heavy commercial vehicles including Volvo FH, FM, and VNL models, as well as Renault Trucks Kerax and Magnum series. It is also compatible with Mack Granite and Pinnacle trucks featuring MP7 or MP8 engines. This part is also fitted to DAF, Iveco, MAN, Mercedes-Benz, and other heavy-duty chassis.

Installation and technical specifications

The unit features three M22x1.5 ports and is rated for a maximum operating pressure of 10 BAR. For proper installation, technicians should ensure all connections are clean and tightened to specification to prevent air leaks. Regular inspection of the valve seating is recommended during routine brake system maintenance to ensure optimal pneumatic performance.
