79379137 Compatible Check Valve — Volvo VHD

What does a check valve do?

This check valve serves as a critical component within the pneumatic brake system, ensuring unidirectional airflow to maintain pressure stability. Manufactured with high-strength components, it is engineered to withstand the rigorous operating conditions found in heavy commercial vehicle air circuits.

Vehicle and engine compatibility

This specific part is compatible with Volvo VHD trucks equipped with D13 engines. It functions effectively within the air brake systems of these heavy-duty vehicles to prevent backflow and maintain system integrity during operation.

Installation and technical specifications

The unit features three M22x1.5 threaded ports (Port 1: M22x1.5, Port 2: M22x1.5, Port 3: M22x1.5) and is rated for a maximum pressure of 10 BAR. When performing installation or maintenance, technicians should verify that the airflow direction matches the circuit requirements and that all connections are tightened to specification.

Maintenance and troubleshooting

Regular inspection of the pneumatic lines and valve seating can help prevent pressure loss in the braking system. For optimal performance, ensure the component is seated correctly within the air circuit to maintain the necessary pressure differentials.
