The DLLA150P207 is a P-type common rail injector nozzle designed for high-pressure direct injection diesel engines. It features a 150-degree spray angle and a long multi-hole (DLLA) nozzle body geometry optimized for MWM TBD 229-EC-6 engine applications. Needle valve material utilizes W6Mo5Cr4V2 high-speed steel for wear resistance at elevated temperatures. Nozzle body material is 18CrNi8 case-hardening steel. Both components undergo vacuum hardening heat treatment achieving a surface hardness of HRC 62-65 to withstand common rail injection pressures exceeding 1800 bar. This nozzle replaces Bosch OE reference 9 430 084 720.
