095420-0281 Common Rail Fuel Pressure Relief Valve for Isuzu Holden Nissan and Construction Equipment
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 diesel vehicle, Isuzu industrial 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.
