79379137 Volvo VNL Check Valve — D13 Engine

What does a check valve do?

This check valve is a critical component within the pneumatic brake system, specifically designed to ensure unidirectional airflow and maintain pressure integrity. It plays a vital role in preventing backflow, which is essential for the stable operation of heavy commercial vehicle air circuits.

Vehicle and engine compatibility

Designed for compatibility with Volvo VNL trucks equipped with D13 engines, this part is engineered to withstand rigorous operating conditions. It features three M22x1.5 ports (Port 1, Port 2, and Port 3) to facilitate precise integration into the existing air lines of the vehicle.

Installation and maintenance

When performing installation or maintenance, technicians should ensure that the M22x1.5 threaded connections are seated correctly to prevent leaks. It is important to verify that the maximum pressure rating of 10 BAR aligns with the specific requirements of the vehicle's pneumatic circuit to maintain optimal braking performance.

System integration

Always verify that the airflow direction matches the installation requirements of the specific brake system circuit. Consult your authorized distributor.
