YNF16773 is a left-hand (LH) valve plate designed for the HPV118 hydraulic main pump. As a core distribution component within the pump, it directs hydraulic oil flow through piston chambers to ensure smooth, efficient power transfer. The plate is CNC-machined with micro-level precision and hardened to resist wear caused by high-pressure fluid dynamics. This replacement part is essential for excavator hydraulic pump rebuilders and is ideal for suppliers looking to stock reliable aftermarket internal pump components.
