Description

What does a pressure limiting valve do?

This pressure limiting valve serves as a critical component within the air brake system of heavy commercial vehicles. It utilizes a piston-and-spring mechanism to regulate air flow by opening at a specific pressure threshold, effectively venting excess air to maintain system stability. Built with high-strength components, it ensures reliable performance under demanding operating conditions.

Vehicle and system compatibility

This component is compatible with DAF and Terex vehicles. It is also designed to work seamlessly with WABCO systems to maintain optimal pneumatic regulation across various heavy-duty applications.

Installation and maintenance

For proper installation, ensure the M22x1.5 ports are correctly aligned and tightened to prevent leaks. The valve operates with an inlet pressure of 12 BAR and provides an outlet pressure of 7.5 BAR, with an adjustable range between 5.8 and 10.8 BAR. Regular inspections of the adjustment settings are recommended during routine maintenance to ensure braking precision.

System troubleshooting

Maintaining correct pressure regulation is essential for the safety of the entire pneumatic system. If inconsistent braking response is detected, verify the valve's setting against the required vehicle specifications.
