Abstract
A modular valve system includes at least one valve housing (40) having standard rate quantities on its opposite ends (38, 42), both on the inner peripheral side and on the outer peripheral side and inside the housing (52). Modular valve components, such as a valve piston (46), at least one energy accumulator (26), a pilot-controlled element, and at least one fluidic connection are mounted in the housing. The housing provides for fixing the valve embodied in the form of a screw-in cartridge for connection to other components.
