7700 920 001 MAN Compatible Compressor Safety Valve

What does a compressor safety valve do?

This compressor safety valve plays a critical role in the pneumatic braking system by regulating pressure levels within the air brake compressor. By maintaining the specified operating pressure, it prevents over-pressurization, ensuring the safety and stability of the braking system during heavy-duty operation.

Vehicle and engine compatibility

This component is designed for a wide range of MAN vehicles, including TGA, TGS I, and TGX I series, as well as LION'S REGIO and LION'S COACH models. It is also fitted to MAN HOCL, NL, NG, SL II, SÜ, and LION'S CITY vehicles. The valve is compatible with WABCO and Bendix systems.

Technical specifications and maintenance

Technical specifications include an M26 port size and a 17 BAR pressure threshold. For optimal performance, workshop technicians should inspect the valve during routine air system maintenance to ensure no debris obstructs the relief mechanism.

System integration

Consult your authorized distributor to verify exact compatibility for your specific engine configuration, such as D2066 or D2676 engines.
