301.01.0022 DAF Unloader Valves

This unloader valve serves a critical function within the heavy commercial vehicle brake system, ensuring regulated air pressure distribution and system stability. Designed for high-pressure environments, the component utilizes high-strength components to maintain operational integrity under demanding duty cycles.

301.01.0022 is the OE-equivalent of the DAF 1518286, MAN 81.52101-6097, MAN 81.52101-6129, MAN 81.52101-6145, MAN 81.52101-6146, MAN 81.52101-6201, MAN 81.52101-6277, MERCEDES BENZ 001 431 61 06, MERCEDES BENZ 001 431 65 06, MERCEDES BENZ 001 431 90 06, MERCEDES BENZ 001 431 91 06, MERCEDES BENZ 002 431 44 06, MERCEDES BENZ 002 431 50 06, MERCEDES BENZ 002 431 84 06, MERITOR S9753035030, RENAULT TRUCKS 5001000006, and WABCO 975 303 5 ⚫ used in DAF, EVOBUS, MAN, MERCEDES BENZ, MERITOR, and RENAULT TRUCKS vehicles.

The technical assembly requires precise attention to port specifications, specifically the M22x1,5 connections on Port 1 and Port 21. Workshop technicians should verify the cut-out pressure settings of 10, ⮾r BAR / 0, ⮾r BAR to ensure seamless integration with existing pneumatic brake systems. Regular inspection of the inflation and recycle valve functions is recommended during standard maintenance intervals to prevent pressure drops.

This component is engineered for compatibility with various heavy-duty truck and bus chassis architectures. It provides stable pneumatic regulation through its robust internal mechanism and optimized port design.
