AKB and AMB systems are hydraulic valve groups designed for folding presses. AKB system is produced for small tonnage and shorter machines. Pressure and directional control valves are all in one block application. Since all the required valves are assembled on a single block, they are compact and easy to install. It is the most economical and most common solution.
The AMB system is designed for heavier tonnage or longer machines. It consists of 3 control blocks in total. These are pressure block and cylinder blocks. In order to achieve synchronization and twist accuracy between the cylinder axes, the necessary valves are carried over the cylinder by means of control blocks. This ensures that synchronization and twist accuracy are maintained, even though the machine capacity increases.
