51 54122 8001 MAN HOCL D2676 Compatible Safety Valve

What does a compressor safety valve do?

This safety valve serves as a critical protection component within the pneumatic system, preventing excessive pressure buildup in the air brake compressor. By utilizing a calibrated spring mechanism, it ensures that pressure remains within safe operating limits, protecting both the compressor housing and the downstream air lines from potential damage caused by overpressure.

Compatibility with MAN HOCL engines

This component is specifically engineered for MAN HOCL vehicles equipped with D2676 engines, including models such as the 24.480 HOCLN, 18.310 HOCL-NL, and 18.430 HOCL. It provides a reliable replacement for original equipment, ensuring the integrity of the braking system under heavy-duty conditions.

Installation and maintenance

Installation should be performed by a workshop technician to ensure the M26 port is correctly seated and that the 17 BAR relief threshold matches the specific requirements of the vehicle's pneumatic circuit. Regular inspection of the valve is recommended to prevent air leaks and ensure consistent relief performance during intensive use.
