Solenoid Valve Manual Overide
Frequently Asked Questions
Q: What is the CR 84344-003 solenoid valve manual override used for?
A: The CR 84344-003 is a manual override solenoid valve designed for Crown electric lift truck hydraulic systems. The manual override feature allows controlled lowering of the load if the normal solenoid control circuit fails, providing emergency descent capability without electrical power to the solenoid coil.
Q: How does the manual override feature on the CR 84344-003 work?
A: The CR 84344-003 includes a mechanical override mechanism that can be manually actuated to open the valve spool without solenoid energization. This allows the operator to lower a raised load in emergency situations when the electrical system is not operational. The override function is independent of the 12VDC solenoid circuit.
Q: Is the CR 84344-003 a direct replacement for the CR 84344-002?
A: The CR 84344-003 and CR 84344-002 are both solenoid valve assemblies for Crown lift trucks, but they are not direct substitutes. The CR 84344-003 includes a manual override feature that the CR 84344-002 does not have. Verify your equipment requirements and hydraulic circuit design before substituting one for the other.
Q: What operating voltage does the CR 84344-003 solenoid coil require?
A: The CR 84344-003 solenoid valve is engineered for Crown electric lift truck electrical systems. Contact us or consult Crown service documentation for the specific operating voltage (12VDC or 24VDC) and electrical specifications for your equipment model.
Q: Can the manual override on the CR 84344-003 be locked out for safety?
A: The manual override feature on the CR 84344-003 allows emergency descent control. Consult Crown safety documentation and your fleet maintenance procedures regarding override lockout protocols and safety interlocks for your specific equipment model and application.
Q: How often should the CR 84344-003 manual override be tested?
A: Manual override solenoid valves should be tested as part of routine safety inspections per Crown service guidelines and ANSI material handling equipment standards. The frequency depends on duty cycle and your facility maintenance schedule. Verify the override mechanism operates smoothly during pre-shift equipment checks.
