51 54122 0003 Safety Valve for MAN TGS I D2676

What does a safety valve do?

This compressor safety valve serves as a critical protection component within the air brake system. It functions by using a calibrated spring mechanism to provide mechanical relief, preventing overpressure conditions within the compressor assembly and ensuring the pneumatic system operates within safe limits.

Compatible vehicles and engines

This component is specifically designed for MAN TGS I trucks equipped with D2676 engines. It is compatible with various models including the 35.480, 33.540, and 41.440 series, providing precise pressure regulation for heavy commercial vehicle applications.

Installation and maintenance

Installation involves a threaded connection to the compressor housing or air line via the M26 port. Technicians should ensure all connections are tightened to specification to maintain the 17 BAR pressure integrity and prevent leaks during high-pressure cycles.

Maintenance and troubleshooting

Regular inspection of the valve is recommended during routine air system maintenance to ensure the relief threshold remains accurate and the sealing components remain intact under high-pressure operating conditions.
