F00R000644 F00R000756 F00R000367 4899831 PLV Pressure Relief Valve For Catrpillar Excavator

This heavy-duty PLV pressure relief valve is made of thick cast iron and weighs 211g. It includes multiple OEM numbers for Catrpillar excavators and MAN diesel engines. It stably releases overpressure to protect high-pressure common rail fuel pipelines.

All these valves have the same dimension and packaging specifications. Every piece is strictly tested for opening pressure. They are durable spare parts for construction machinery and heavy truck common rail fuel systems.

1. Q: Can the MAN engine relief valve be installed on my Catrpillar excavator?
   A: No. Each OEM number corresponds to a fixed opening pressure. The valve for MAN engines cannot be used on Catrpillar excavators without matching the part code.
2. Q: Why is this 211g PLV much heavier than ordinary small relief valves?
   A: It adopts an extra thick iron shell to bear the ultra-high rail pressure of construction machinery, suitable for long-term heavy-load working conditions.
3. Q: What problems will mismatched PLV cause on my MAN truck engine?
   A: Unmatched opening pressure will lead to unstable fuel rail pressure, insufficient power, and even damage the high-pressure oil rail and fuel injectors.
