YNF16868 2036441 Valve L HPV050 Left Valve Plate for Hitachi EX100-5 EX120-5 Hydraulic Pump

The YNF16868 Valve L, equivalent to 2036441, is the left-side valve plate for the HPV050 hydraulic pump, widely used on Hitachi EX100-5 and EX120-5 excavators. As a key part of the pump’s rotating group, this valve plate directs hydraulic oil flow with high precision, ensuring smooth pumping, stable pressure, and efficient machine operation. When a valve plate becomes worn or scratched, hydraulic leakage, pressure loss, overheating, and slow response often occur.

Manufactured using heat-treated alloy steel and refined CNC grinding, the YNF16868 valve plate provides excellent flatness, wear resistance, and sealing performance. Its durable surface ensures stable oil distribution even under continuous high-pressure workloads and long operating hours.

This left valve plate is preferred by hydraulic pump rebuilders, aftermarket distributors, and excavator maintenance workshops. Replacing the worn valve plate restores pressure, improves pump efficiency, and extends overall hydraulic system life.
