Komatsu 3BA-61-51411 Control Valve Ass’y FB10/14EX-8
Overview
The 3BA-61-51411 Control Valve Ass’y is the hydraulic control valve assembly specified for Komatsu’s 8-series electric counterbalance forklifts. Mounted in the lift hydraulic circuit, it directs pressurized oil to the mast cylinders and governs how smoothly the forks lift, hold and lower a load. When a control valve wears internally, operators often notice drifting forks, sluggish lifting, jerky lowering or pressure loss under load. Replacing the faulty unit with the correct 3BA-61-51411 for FB10/14EX-8 and its sister models restores precise, responsive hydraulic control and helps protect the rest of the lifting system from abnormal stress.
Compatibility
This CONTROL VALVE ASS’Y is produced for the Komatsu FB10/14 and FB15/18 8-series electric forklift families, covering 1.0-1.8 ton battery-powered trucks:
- FB10/14EX-8 series – FB10/14EX-8 and FB10/14EXF-8
- FB15/18EX-8 series – FB15/18EX-8, FB15/18EX-8-EC and FB15/18EXF-8
- FB15/18EXG-8 series – FB15/18EXG-8, FB15/18EXG-8-EC and FB15/18EXGF-8
Komatsu occasionally updates components mid-production, so we recommend confirming the part number 3BA-61-51411 against your truck’s model and serial number, or the number stamped on the valve you are replacing, before ordering. Our team is happy to help you verify fitment.
Quality and Reliability
The 3BA-61-51411 CONTROL VALVE ASS’Y is manufactured to match Komatsu’s original specifications for port sizing, spool dimensions, operating pressure and mounting points, so it installs as a direct replacement without modification. Internal components use wear-resistant materials and are engineered for leak-free sealing and consistent pressure response across the duty cycle. On a safety-critical hydraulic component like a control valve, that dimensional accuracy matters: correct spool tolerances keep lift and lowering speeds predictable even with a full-capacity load on the forks.
Installation and Maintenance Tips
- Depressurize the hydraulic system and fully lower the mast before starting work; on these electric trucks, disconnect the battery as well.
- Photograph hose and port routing before removal, and cap open lines to keep contamination out of the circuit.
- Replace the O-rings and seals at the ports rather than reusing old ones, and tighten fittings to Komatsu’s torque specifications.
- Refill with clean hydraulic fluid of the specified grade, bleed air from the circuit, then cycle lift and lowering several times and inspect for leaks before returning the truck to service.
