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.
This mechanical fuel pressure limiting valve serves the pressure relief circuit in compatible diesel common rail injection systems. Installed at the fuel rail, it provides a controlled relief path when rail pressure reaches the limiter setting, helping protect the injection circuit from excessive pressure. It is a separate mechanical component, distinct from the electrical rail pressure sensor and pump metering solenoid.
The valve is supplied as a new aftermarket replacement for the documented Isuzu engine and related construction-equipment configurations. The threaded interface, sealing arrangement and original limiter reference must match the installed rail. The application table includes the available engine families, industrial emissions variants and equipment models linked to the verified service references; an equipment model alone does not establish compatibility with every engine or rail version. Product photographs show the supplied component. A one-year warranty is provided.
