FAQ Guide – FUJI XS03764 V12 Working Head Mechanical Valve SPOOL
General Information
Q1: What is XS03764 Mechanical Valve SPOOL used for?
A:
The XS03764 SPOOL is a critical internal component of the mechanical valve assembly inside the FUJI NXT V12 working head. It is responsible for controlling the vacuum and air pressure switching, enabling accurate pick-and-place nozzle operation.
Function & Working Principle
Q2: What is the function of the mechanical valve spool?
A:
Controls pneumatic flow inside the V12 head.
Switches between vacuum (for picking components) and positive pressure or air blow (for component release or nozzle cleaning).
Ensures precise and reliable head pneumatic performance.
Machine Compatibility
Q3: Which machines is XS03764 compatible with?
A:
FUJI NXT II
FUJI NXT III
FUJI NXT V series (with V12 working head)
Installation & Replacement
Q4: When should the XS03764 spool be replaced?
A:
Air leaks during pick or placement.
Vacuum not holding properly.
Positive air not functioning correctly.
Nozzle misfires or stuck.
Maintenance cycle indicates wear (typically after 12–24 months, depending on usage).
Q5: How to replace the spool?
A:
1. Power off and depressurize the machine.
2. Open the V12 head’s pneumatic valve assembly.
3. Remove the valve body and access the spool.
4. Check the condition of the spool (XS03764), valve body (XS03765), and O-rings (XS03766).
5. Install the new spool, lubricate with appropriate pneumatic grease.
6. Reassemble the valve, check for air leaks.
Common Issues & Troubleshooting
Q6: What are common failure symptoms?
A:
Vacuum loss on specific nozzles.
Slow air release or stuck nozzle movements.
Persistent air blowing when idle.
Increased pick errors or placement failures.
Q7: What causes spool failure?
A:
Long-term wear of the spool surface.
Dirt, flux residue, or oil contamination inside the valve.
O-ring degradation leading to leaks.
Incorrect lubrication or lack of maintenance.
Maintenance Tips
Q8: How to maintain the mechanical valve spool?
A:
Clean the valve assembly regularly (recommended every 3–6 months).
Replace spool and seals preventively after 12–24 months or upon wear signs.
Use only approved pneumatic grease (FUJI recommended types).
Keep the compressed air supply dry and clean with proper filters.
