Description
The Multi-circuit Protection Valve serves as a critical component within the pneumatic brake system of heavy commercial vehicles, ensuring pressure stability across multiple circuits. This component is designed to protect the braking system from pressure fluctuations and maintains the integrity of the air supply during operation.
The Vaden Original 303.02.0058 is an OE equivalent of the FAUN 99707007310 and WABCO 9347050040 components used in heavy-duty vehicles. This part features a specific port configuration including M22x1,5 and M12x1,5 connections to match exact technical requirements. It is designed to work seamlessly with FAUN and WABCO hardware architectures.
Technicians should verify the port sizes and pressure ratings during installation to ensure optimal system performance. The valve operates with an opening pressure of 7,5 BAR for ports 23/24 and a closing pressure of 6,6 BAR for ports 21/22. Regular inspection of the pneumatic lines connected to these ports is recommended to prevent leaks or pressure drops in the braking circuit.
Regular maintenance of the pneumatic brake system ensures that these protection valves perform their duty in preventing system failures during transit.
