Product Detail

Valve Assy – Part No. 56B-43-12402 for Komatsu HD-785 Dump Truck

This valve assembly is a genuine replacement component specifically designed for the Komatsu HD-785 dump truck. It is a critical hydraulic control unit typically used in the brake system, suspension circuit, or dump body hoist control. The assembly consists of a precision-machined cast iron body, internal spools or poppets, springs, seals, and pilot ports, all factory-assembled to exact Komatsu specifications. This valve assembly regulates hydraulic flow and pressure to ensure safe and reliable operation of heavy-duty functions such as braking, load holding, and body dumping. Using an authentic Komatsu 56B-43-12402 valve assembly guarantees correct fitment, consistent performance under extreme loads, and long service life. Regular inspection for external leakage, spool sticking, or pressure drop is recommended, and replacement should be made with genuine Komatsu parts to maintain machine safety and productivity.
