51 54122 0011 Compressor Safety Valve for MAN TGA

What does a compressor safety valve do?

This compressor safety valve serves as a critical protection component within the air brake system, preventing excessive pressure buildup within the compressor assembly. By utilizing a calibrated mechanical opening mechanism, it ensures that the air pressure remains within safe operational limits, protecting both the compressor and the pneumatic lines from potential damage.

Compatible MAN TGA models

This component is specifically designed for MAN TGA trucks equipped with D2066 engines. It is compatible with various models including the 33.350, 35.430, and 41.390, among others. This part ensures precise pressure regulation across these heavy commercial vehicle applications.

Installation and maintenance

Installation requires careful attention to the M26 port threading to ensure a secure, leak-free connection to the compressor housing. Technicians should verify that the 17 BAR pressure rating aligns with the specific requirements of the vehicle's pneumatic system during routine maintenance or replacement.

System protection

Regular inspection of the safety valve is recommended to ensure it vents correctly and shows no signs of debris accumulation that could hinder its performance.
