Valve plate for Hitachi KH180

The valve plate 3022866 acts as a critical interface within the hydraulic pump or motor assembly of the Hitachi KH180 crawler crane. Its primary function is to direct the flow of hydraulic fluid between the rotating group and the pump or motor housing. By providing a precise contact surface for pistons or vanes, the plate manages the timing and path of fluid movement, which is necessary for maintaining volumetric efficiency and operational pressure within the machine's hydraulic system.

This component is compatible with the Hitachi KH180 model. It is engineered to meet specific geometric requirements for port alignment and surface flatness to ensure proper operation of the crane's lifting and travel functions. Proper installation and the use of clean hydraulic fluid are necessary to maintain the integrity of the sealing surfaces and prevent internal leakage.

In hydraulic machinery, valve plates are used to control the intake and discharge cycles of fluid. They facilitate the transition of hydraulic energy into mechanical motion for motors or the generation of pressure for pumps, ensuring that the system operates with the intended flow characteristics and efficiency.
