Definitions

  • the invention relates to a valve assembly having a modular manifold assembly having a plurality of juxtaposed in a rowing direction and each in a joint area facing each other mating joint modules, of which at least several are each formed as a valve support module carrying at least one electrically actuated valve unit wherein each of said valve units has internal valve passages for feeding and discharging a working fluid and at least one valve working channel for connection to an external consumer to be actuated, and wherein each valve carrier module is connected to at least one valve carrier working channel connected to a valve working channel of the valve unit located thereon is interspersed, to which an external consumer to be actuated can be connected by means of at least one consumer connection opening arranged on the outside of the distributor module.
  • One from the DE 19711227 C2 known valve assembly of this type includes a distribution base called a mounting base having a plurality of juxtaposed in a Aukahungsraum and mechanically fixed to each other distribution modules. Electrically actuated valve units with internal valve channels are mounted on the manifold assembly. Some of the distributor modules are as valve carrier modules each designed and carry one of the valve units, wherein they are interspersed in each case by at least one valve carrier working channel which communicates with a valve working channel of the associated valve unit.

By electrical actuation of the valve units, the respectively connected consumer can be actuated as desired, wherein the working fluid used for this purpose is fed through and discharged through valve channels of the valve units.
  • the achievable working capacity of the consumer (s) to be actuated depends significantly on the size of the valve units and more precisely on the flow cross sections of the valve channels.
