Valve arrangement

A valve arrangement comprising at least one valve unit possessing a main valve and at least one pilot valve for operation of such main valve and fitted with an electrically operated actuating unit, a base plate for such valve unit, such base plate having two limbs extending to the same side and delimiting an accommodation space, valve ducts extending in said base plate, such valve ducts including at least one supply duct, at least one venting duct and at least one power duct, said valve ducts being in communication with a valve spool receiving space of the main valve, which receives a valve spool of said main valve able to be moved axially between different switching positions, wherein the base plate forms the housing of the main valve and contains the valve spool receiving space with the valve spool, the base plate is divided into a central part and two terminal parts mounted on the opposite end surfaces of the central part, each terminal part constituting both an end cover for the valve spool receiving space and also one of the limbs delimiting the accommodation space, and furthermore at least one section of a pilot duct extends in the terminal parts, such pilot duct opening into the accommodation space at the associated limb, in which space at least an actuating unit of the at least one pilot valve is arranged, wherein the central pan of the valve unit possesses a projection extending into the accommodation space, such projection constituting a partition dividing the accommodation space into two individual spaces, each individual space being suitable for receiving at least the actuating unit of the at least one pilot valve.
