Hydraulic manifolds are a generalization installation unit of the standard sandwich valves, surrounded by side fittings connected with the implementation of components, such as modular valves, or cartridge type valves. The inner line communicates with valve manifolds, composed of a variety of basic circuits. Integrated hydraulic manifolds for the connection between the block and the block face, long bolts stacks of loaded up for several blocks overlapping, forming the parts of hydraulic system..
