CR 091679

Frequently Asked Questions

Q: What is the CR 091679 solenoid valve and what does it control?
A: The CR 091679 is an OEM solenoid valve for Crown electric lift truck hydraulic systems. It controls hydraulic fluid flow using a 24VDC electromagnet actuator and is rated for high-cycle switching in lift, lower, and tilt circuits.

Q: What voltage and control specifications does the CR 091679 require?
A: The CR 091679 operates on 24VDC control voltage with a robust electromagnet actuator. Verify that your hydraulic control circuit supplies clean 24VDC power. Low voltage or high ripple will cause sluggish response or solenoid failure.

Q: What is the flow rating and pressure range of the CR 091679?
A: Crown solenoid valves like the CR 091679 typically handle flows from 10 to 30 GPM and operate in pressure ranges from 500 to 3000 PSI depending on the specific cavity. Check your service manual for the exact pressure rating for your model.

Q: How do I know if the CR 091679 solenoid valve is faulty?
A: Signs of solenoid failure include slow or no response to lift or lower commands, hissing or venting from the valve, leaking hydraulic fluid around the coil, or complete loss of function in one circuit. Test with a multimeter to verify coil continuity.

Q: What is the expected cycle life of the CR 091679?
A: The CR 091679 is rated for high-cycle duty, typically rated for 1 to 3 million cycles. Actual lifespan depends on duty cycle, fluid contamination, voltage stability, and proper maintenance. Replace if switching response degrades or solenoid overheats.
