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.

1110010024 Common Rail Pressure Relief Valve for Selected MAN Truck and Bus Application

1110010024 Common Rail Pressure Relief Valve for Selected MAN Truck and Bus Application

This common-rail pressure relief valve is a protective component in the high-pressure diesel fuel circuit. When fuel pressure rises above its calibrated limit, the valve opens to release excess fuel to the return path, helping keep system pressure within its designed operating range.
Listed for selected MAN truck and bus configurations using common-rail diesel systems. The required valve specification depends on the engine and vehicle version. Check the marking on the installed valve and compare the engine and manufacturer references below before ordering.

1110010028 Common Rail Pressure Limiting Valve for Selected Cummins, Volkswagen and New Holland Applications

1110010028 Common Rail Pressure Limiting Valve for Selected Cummins, Volkswagen and New Holland Applications

This common-rail pressure limiting valve is a protective component in the high-pressure fuel circuit. When fuel pressure exceeds its calibrated opening threshold, the valve releases excess fuel through the return path to limit pressure within the injection system.
Catalogued for selected diesel applications including Volkswagen Delivery vehicles with Cummins engines and New Holland T4 equipment. Fitment depends on the rail, engine code and production version. Compare the installed valve marking and engine details with the references below before ordering.

1110010026 Common Rail Fuel Pressure Limiting Valve for Diesel Vehicles and Equipment

1110010026 Common Rail Fuel Pressure Limiting Valve for Diesel Vehicles and Equipment

This mechanical fuel pressure limiting valve forms part of the protection circuit in compatible diesel common rail injection systems. Installed at the rail limiter port, it provides a relief path when fuel pressure reaches the limiter setting. Its function is separate from electronic pressure measurement and active rail pressure regulation. The valve body incorporates a threaded mounting section and sealing arrangement for the corresponding rail connection.

The product is supplied as a new aftermarket replacement single valve. The application table retains the documented vehicle and equipment configurations, including available engine codes, output ratings, production limits and VIN restrictions. Where a valve-specific date restriction is provided, it takes priority over the wider vehicle production period. Open-ended or unavailable year ranges are shown as ——. Match the original pressure limiter reference and rail configuration before ordering. A one-year warranty is provided.
