Valve plate for Demag AC80-1

The valve plate, part number 421 457 12, serves as a component within the hydraulic or pneumatic systems of the Demag AC80-1 crane. It directs and controls the flow of hydraulic oil or compressed air through the valve assembly, which enables the activation and deactivation of specific crane functions. By maintaining proper internal flow paths, this plate facilitates the operation of hydraulic cylinders and motors throughout the machine.

This component is specifically compatible with the Demag AC80-1 model. It is engineered to ensure correct sealing within the valve block to prevent fluid leakage and maintain system pressure. Proper installation of this valve plate supports the consistent response of the crane's hydraulic systems during lifting, extension, or slewing movements.

In hydraulic systems, a valve plate typically acts as an interface between the valve body and the moving parts of the valve mechanism. It defines the ports and passages that allow fluid to enter or exit specific chambers, thereby governing the pressure and direction of the hydraulic circuit. Maintaining the integrity of these passages is necessary for the overall control and efficiency of the hydraulic system.
