51 54122 0007 MAN TGS I D2676 Compressor Relief Valve

What does a compressor safety valve do?

This compressor safety valve serves as a critical protection component within the pneumatic brake system, preventing excessive pressure buildup. By utilizing a calibrated spring mechanism, it provides a reliable mechanical opening to vent air when thresholds are exceeded, ensuring the integrity of the air brake system during heavy-duty operation.

Vehicle and engine compatibility

Specifically designed for MAN TGS I models equipped with D2676 engines, this part ensures precise pressure regulation. It is compatible with various TGS I configurations including 35.480, 33.540, and 41.440 models. This component is engineered to meet the rigorous demands of heavy commercial vehicle environments.

Installation and maintenance

The valve features an M26 port connection and is rated for 17 BAR operating pressure. During installation, technicians should ensure the threaded connection to the compressor housing is secure and that all sealing surfaces are clean to prevent air leaks. Regular inspection of the relief threshold is recommended during routine pneumatic system maintenance.
