ABSTRACT:
The control block consists of four seat valves arranged in pairs above one another and opposite one another in two planes parallel to the base surface of the control block, the valves located diagonally opposite one another being controllable in pairs via a pilot valve. The logical combination of the invididual elements makes it possible to construct a compact, space-saving and handy control unit with a sealing surface arranged according to the customary standard pattern.
