This fuel metering valve controls the quantity of diesel supplied to the pumping elements of a compatible high-pressure injection pump. Its electrically operated mechanism responds to the engine management system, adjusting inlet flow as operating demand changes. Metering fuel at the pump inlet is part of the common rail pressure-control process and differs from measuring pressure with a sensor or regulating it at the rail.
The replacement component is intended for the documented vehicle, equipment and engine configurations listed below. Original valve identification and the installed injection-pump assembly determine the appropriate replacement. The application information records available model details, engine specifications and catalogue periods. Match the original component marking and pump number before ordering, because model names and engine displacement alone do not establish compatibility with every build.
This common-rail pressure limiting valve helps protect the diesel fuel circuit by providing a controlled relief path when fuel pressure reaches the valve's calibrated opening condition. Excess fuel is directed through the designated return circuit, helping keep system pressure within its designed operating range.
Catalog listings associate this part reference with selected Cummins engine applications and MAN truck and bus applications, as well as Neoplan Centroliner buses. Fitment depends on the installed fuel-system configuration; compare the complete reference on the original component and confirm the vehicle or engine details before ordering.
This common-rail pressure relief valve protects the high-pressure diesel fuel circuit. When rail pressure exceeds the valve's calibrated opening threshold, the valve opens and directs excess fuel to the return line, helping keep system pressure within its intended range.
It is listed for selected diesel engines, commercial trucks, and buses. Fitment varies with the engine, fuel-rail assembly, and vehicle configuration; compare the installed valve reference and vehicle details with the applications below before ordering.
