0281006640 Common Rail Fuel Pressure Control Valve DRV for JAC 1035 1040 and 1042

The common rail pressure control valve is part of the diesel fuel injection system. It regulates pressure in the rail so fuel can be delivered to the injectors at the pressure required by the system. The valve is used in service and repair of compatible common rail assemblies, where correct matching to the original valve and rail configuration is important.
This part is listed for selected JAC light truck applications using the 4DE1 GreenJet diesel engine. Vehicle and engine configurations can differ by market and production specification, so confirm the original part reference and engine identification before ordering. No pump number or additional interchange number is listed here because a reliable OE-linked confirmation was not found.

0281006209 Common Rail Pressure Control Valve for Ram and Jeep 3.0L Diesel

This common rail fuel pressure control valve is a component of a diesel fuel injection system. It regulates fuel pressure in the rail, where pressurized fuel is distributed to the injectors. The valve is fitted within the rail assembly and works as part of the engine's fuel management system. Its pressure regulation role is linked to the original fuel system configuration and the valve reference specified for that installation.

The application table identifies documented vehicle variants and includes engine specifications, displacement and production dates where these are available. Reference numbers are grouped by their catalogue manufacturer to support identification. Associated fuel rail numbers are listed as assembly information and are distinguished from standalone valve references. Match the reference on the removed valve and confirm the rail arrangement, electrical connection and vehicle specification before selecting a replacement.

0281006034 Common Rail Pressure Control Valve for Opel Chevrolet Saab Applications

This pressure control valve regulates fuel pressure in a diesel common rail injection system. The component is fitted to the fuel rail and forms part of the high-pressure fuel distribution circuit. It is catalogued as a pressure regulator and control valve, with a separate identity from the pressure sensor installed on the same rail assembly.

The rail-mounted regulator provides the pressure-control function within the injection system. Product identification follows the standalone component reference and the matching engine configuration. The specifications separate the valve from complete fuel rails, while the application table retains the body styles, engine variants and catalogued periods supplied by the inspected vehicle and component records.
