095420-0670 Common Rail Fuel Pressure Relief Valve for Toyota Mechanical Rail Systems

This mechanical common rail pressure relief valve provides the overpressure relief path in compatible diesel fuel rail assemblies. Its threaded body fits the limiter port, while the extended metal outlet connects with the relief circuit. It is intended for fuel systems that use a mechanical pressure limiter and is separate from an electrical rail pressure sensor or electronically operated pressure discharge valve.

Supplied as a new aftermarket replacement, the valve is intended for the documented earlier fuel rail configurations. Vehicle families can use different fuel rail and emissions-system versions, so the original rail reference and installed valve configuration must match. The application table distinguishes the documented regional hardware configuration from broader rail catalogue families. Related complete rail numbers are listed separately for identification. Product photographs show the supplied valve. A one-year warranty is provided.

0928400584 Fuel Metering Valve for Renault Nissan Opel and Vauxhall Diesel Applications

0928400584 Fuel Metering Valve for Renault Nissan Opel and Vauxhall Diesel Applications

This fuel metering valve controls the amount of diesel fuel admitted to a compatible high-pressure injection pump. Its electrically operated mechanism responds to the engine management system, varying the inlet supply as fuel demand changes. This inlet-metering function forms part of common rail fuel-pressure control and is distinct from the function of a rail-mounted pressure sensor.

The replacement is intended for the documented diesel vehicle configurations listed below. The application table retains engine identifiers, power ratings and catalogue production periods where those details have been verified. Match the original valve marking and injection-pump identification before ordering, because different fuel-system builds may be fitted within a vehicle model range.

095420-0140 Common Rail Fuel Pressure Relief Valve for Komatsu Equipment and Engines

095420-0140 Common Rail Fuel Pressure Relief Valve for Komatsu Equipment and Engines

This mechanical fuel pressure limiter forms part of the pressure protection circuit in compatible diesel common rail systems. Installed at the rail pressure limiter port, it provides the relief path when rail pressure reaches the limiter setting. It is a separate component from the rail pressure sensor and the flow limiters used at the individual fuel outlets.

Supplied as a new aftermarket replacement, the valve is intended for the documented equipment and engine configurations with a matching original pressure limiter reference. The application table retains the available machine and engine information without assigning an engine to a machine where the exact pairing is not documented. The original threaded connection, sealing arrangement and fuel rail configuration must match the replacement. Product photographs show the supplied single valve. A one-year warranty is provided.

1110010020 Common Rail Pressure Relief Valve for Cummins Ford MAN and Volkswagen Applications

1110010020 Common Rail Pressure Relief Valve for Cummins Ford MAN and Volkswagen Applications

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.
