51 54122 0011 Compressor Safety Valve compatible with MAN HOCL

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. By utilizing a mechanical opening mechanism, it maintains safe operating limits to protect both the compressor assembly and the pneumatic lines from overpressure during intensive use.

Compatible MAN HOCL vehicles

This specific component is designed for MAN HOCL trucks, including models such as the 18.310 HOCL-NL, 18.400 HOCL, 18.430 HOCL, 18.440 HOCL, 24.440 HOCLN, 18.360 HOCL, and 18.320 HOCL-NL. It is engineered to match the exact requirements of these heavy commercial vehicle applications.

Installation and maintenance

The valve features an M26 port connection and is rated for a 17 BAR operating pressure. During installation, technicians should ensure that the threaded connection is seated correctly to prevent air leaks and verify that the relief threshold aligns with the vehicle's pneumatic system requirements.

System protection and inspection

Maintaining correct pressure regulation is vital for braking performance and road safety. Always check for signs of air leakage around the housing or gasket during routine inspections to ensure the system remains airtight.
