1. A valve for installing in a valve bore of a housing or of a valve block, the valve comprising:
a valve bushing configured to be inserted into the valve bore; a valve piston guided in an axially movable manner in the valve bushing, the valve piston configured to project axially above the valve bushing by means of an actuating section; and a valve cover arranged over the valve bore, the valve cover together with the actuating section of the valve piston forming at least one actuating pressure space, the valve cover divided axially into at least two components, an intermediate cover configured to guide the actuating section in a main bore and a functional cover provided on the intermediate cover on the side remote from the valve bushing, said functional cover having at least one control channel, wherein: control connections and/or fastening means are arranged with respect to the main bore of the intermediate cover such that changing an alignment of the intermediate cover in predetermined angular steps about a longitudinal axis of the valve bore connects a control channel of the intermediate cover to different control connections of the housing or valve block.
