51 54122 0011 MAN LION´S COACH Compressor Safety Valve

What does a compressor safety valve do?

This safety valve serves as a critical component within the air brake compressor system, managing internal air pressure to prevent over-pressurization. Built with high-strength components, it ensures the pneumatic circuit remains within safe operating limits during heavy-duty service cycles.

Vehicle compatibility and application

Specifically designed for MAN LION´S COACH models, this component is compatible with the vehicle's air brake assembly. It maintains operational reliability in demanding commercial environments where consistent pressure regulation is vital.

Installation and technical specifications

The unit features an M26 port size and is rated for a 17 BAR operating pressure. For proper installation, technicians should ensure the compressor housing and air lines are free of debris and that the threaded connection is seated correctly according to workshop standards.

Maintenance and troubleshooting

Regular inspection of the safety valve can help prevent system failures caused by excessive pressure buildup. If pressure regulation issues arise, verify the integrity of the valve's internal spring mechanism.
