Komatsu 3BA-61-51211 CONTROL VALVE ASS’Y for FB15/18EX-8

Overview

The 3BA-61-51211 CONTROL VALVE ASS’Y is a Komatsu hydraulic control valve assembly for the 8-series electric forklift range. Mounted in the hydraulic circuit, it directs oil flow and pressure to the lift and tilt functions, giving the operator smooth, proportional control over each load. If your truck shows slow or erratic lift response, drifting forks, or internal leakage, fitting the correct 3BA-61-51211 assembly restores dependable hydraulic performance and helps protect the rest of the system.

Compatibility

The 3BA-61-51211 for FB10/14EX-8 and related models fits Komatsu 8-series electric counterbalance forklifts across two capacity groups:

• FB10/14EX-8 series – 1.0-1.4 ton trucks, including the FB10/14EX-8 and FB10/14EXF-8
• FB15/18EX-8 series – 1.5-1.8 ton trucks, including the FB15/18EX-8 with EC variants (FB15/18EX-8-EC and FB15/18EXG-8-EC) and the F-suffix versions FB15/18EXF-8, FB15/18EXG-8 and FB15/18EXGF-8

Revision codes and suffixes can vary between markets, so always confirm your truck’s model and serial plate before ordering. Our team can verify fitment against your chassis number so you receive the correct valve assembly the first time.

Quality and Reliability

This control valve assembly is manufactured to Komatsu specification for the EX-8 series, with materials and sealing components selected for continuous electric-forklift duty. Precision-machined internal passages support consistent spool movement and stable pressure control, while durable seals resist internal and external leakage through daily warehouse and loading-dock cycles. Choosing the specified 3BA-61-51211 CONTROL VALVE ASS’Y rather than an unverified substitute helps preserve original hydraulic response, reduces the risk of contamination-related wear, and keeps your Komatsu truck operating as its engineers intended.

Installation and Maintenance Tips

• Relieve all hydraulic pressure and isolate the power source before removing the old valve assembly.
• Cap open hoses and ports immediately to keep dirt and debris out of the circuit.
• Replace O-rings and seals during fitting, and inspect hoses and fittings for wear while the circuit is open.
• Tighten fittings and mounting bolts to Komatsu torque specifications and refill with clean hydraulic fluid of the correct grade.
• After installation, cycle the lift and tilt functions slowly, check for leaks, and re-check fasteners after the first operating hours.
• Inspect the valve area periodically so early signs of seepage or slow response can be addressed promptly.
