Frequently Asked Questions
Q: What does the CR 117080 relief valve kit do?
A: The CR 117080 is a factory OEM hydraulic pressure relief valve kit designed for Crown PE 3000 Series electric pallet jacks. It limits maximum system pressure by diverting excess hydraulic fluid when pressure exceeds the preset threshold, protecting the lift pump and cylinders from overpressure damage.
Q: Is the CR 117080 compatible with other Crown models besides PE 3000 Series?
A: No. The CR 117080 is designed exclusively for Crown PE 3000 Series rider electric pallet jacks. It mounts directly to the factory hydraulic manifold and is not compatible with other Crown series or third-party equipment. Always verify your model number before ordering.
Q: What components are included in the CR 117080 relief valve kit?
A: The CR 117080 kit includes a spring-loaded pilot-operated relief valve, polyurethane and nitrile seals, mounting hardware, and port adapters for manifold installation. All components are pre-assembled to OEM specifications.
Q: Can the CR 117080 pressure setting be adjusted in the field?
A: The CR 117080 ships factory-set to Crown PE 3000 Series OEM specification. Field adjustment is possible with proper hydraulic pressure gauges and procedures, but unauthorized adjustment can compromise system safety. Consult your equipment manual or contact technical support before adjusting.
Q: How long does the CR 117080 relief valve typically last?
A: With proper maintenance and clean hydraulic fluid, the CR 117080 relief valve typically lasts 5 to 7 years or 5000 to 8000 operating hours. Lifespan depends on fluid condition, operating pressure cycles, and contamination levels. Replace seals every 2 to 3 years during routine maintenance.
