803605463 float solenoid coil for XCMG ZL50G/ZL50GL Wheel Loader

product parameters

Product Name: Float Solenoid Coil
Part No.: 803605463
Applicable Model: XCMG ZL50G, ZL50GL Wheel Loader
Type: Electromagnetic coil (pilot valve)
Installation Position: Pilot valve body
Function: Converts electrical signal into electromagnetic force to drive pilot valve spool
Working Voltage: 24V

Applicable Scenarios

Widely used in quarry, aggregate yard, and earthwork construction sites with frequent shifting and hydraulic operations. It is a key electromagnetic accessory for ensuring normal pilot control function and reliable shifting.

▪ Direct electrical-magnetic-hydraulic conversion for pilot control
The coil receives electrical signals to generate electromagnetic force driving the pilot valve spool with direct response, helping achieve accurate shifting or hydraulic actuation control.

▪ Manufactured to OEM electrical parameters for control system match
Coil electrical parameters are designed for the ZL50G/ZL50GL control system, working when connected to the original circuit and reducing abnormal actuation from parameter mismatch.

▪ Mounting matches pilot valve body for easy replacement
Mounting dimensions and interfaces follow the original pilot valve design, requiring no valve body or circuit layout modification during replacement and shortening on-site repair time.

▪ Can be stocked with pilot valves, seals, and related accessories
Can be stocked together with pilot valve bodies, seal rings, harness connectors, and related accessories for the same model, facilitating complete procurement during hydraulic control system maintenance.

FAQ 

Q：When does a float solenoid coil need replacement?
A: Replace when the coil burns out (abnormal resistance or open circuit), electromagnetic force is insufficient causing weak spool actuation, connector contact is poor causing intermittent operation, or the coil housing is damaged or leaks oil.

Q：Is pilot valve failure always caused by the coil?
A: Not necessarily. Check whether the control system outputs electrical signals, harness connectors are loose, and the spool is seized first. Inspect the coil for burnout or insufficient electromagnetic force after confirming electrical signals and spool are normal.

Q：What to note during float solenoid coil installation?
A: Confirm the coil working voltage matches the original system (typically 24V). Clean the valve body mounting surface and check seal integrity before installation. Align connectors with locks engaged during wiring.

Q：How to maintain the float solenoid coil daily?
A: Regularly check coil connectors for looseness and wiring for wear. Observe whether shifting or hydraulic actuation is normal. Check coil appearance and resistance during hydraulic system maintenance.
