- the channel is connected to a stub, which opens at two opposite surfaces of the base plate.
- DE 102 42 726 A1 discloses a valve plate with poppet valves integrated therein, which can be switched by upstream control valves and associated control channels, wherein the control channels are bounded by two opposing channel plates, one of which is exchangeable to different interconnections of the control channels and thus to allow different switching functions for the poppet valves.
- a solenoid valve which has a NEN of valve channels interspersed body and a magnetic device having a magnetic head. Between the magnetic head and the base body, which are arranged successively in the direction of a main axis, a valve chamber communicating with a plurality of valve channels is arranged.

It is provided that the 2/2-way valves are designed as valve units, in which the actuating means with a Valve section forms a compact unit which is placed on the loading surface of the channel body, wherein the valve portion includes the first and the second fluid port and a valve seat against which the valve member is movably arranged to the free fluid channel cross section between the first and the second fluid port between a Lock position and a release position to influence.
- the 2/2-way valves are formed completely outside the channel body and are mounted as compact units on the mounting surface of the channel body.
- the structure of the channel body is simplified because no provision must be made to form a valve seat or for receiving and storing valve elements.
- this ensures an advantageous interchangeability of the 2/2 way valves in case of damage, since the valve units can be removed and replaced as a complete assembly.
- the 2/2 way valves comprise, in addition to the electrically controllable actuating means, the valve section which serves for the fluid guidance.
- the valve section has a fluid channel, which opens on an outer surface into two spaced-apart fluid ports.
- a valve seat is formed, which allows a sealing engagement of the valve member to block the free cross section of the Fluidka- channel.
- the valve member can be moved by a force exerted by the actuating means from a sealing contact with the valve seat in a release position in which the valve seat and thus the fluid channel cross-section are released.
- the actuating means can therefore be the valve influence member so that this occupies either the blocking position or the release position.
- the actuating means may be arranged such that it allows a free adjustment of the position of the valve member between the sealing blocking position and the release position.
- the 2/2-way valve allows a freely selectable adjustment of the available fluid channel cross section between the fluid connections in the manner of a continuous valve or a proportional valve.
- the outer surface of the valve section, in which the fluid connections lead out, is provided for surface sealing engagement with the mounting surface of the channel body.
- the fluid connections are designed for communicating connections with fluid channels in the channel body.
- valve units of the valve module are all constructed in an identical manner and are each attached to the channel body with discrete fasteners, for example screws. Due to the identical design of the valve units and the individual attachment to the ductwork, it is easier to replace individual valve units in the event of damage.
- the 2/2 -way valves prefferably have an oblong cross-section in a cross-sectional plane parallel to the fitting surface whose cross-sectional main extension is aligned at least substantially perpendicular to the stacking direction and that the cross-sectional main extents of the 2/2 -way valves of a valve module are coaxial with one another. are directed. This ensures that the 2/2-way valves have a small extent in the stacking direction.
- a plurality of valve modules can be assembled into a compact valve device.
- the 2/2-way valves in the cross-sectional plane parallel to the assembly surface have a thickness extent in the stacking direction which is a fraction, preferably less than 50 percent, particularly preferably less than 35 percent, in particular less than 25 Percent, which is the cross-sectional main extension.
- the 2/2-way valves are substantially parallelepiped-shaped and surfaces of the 2/2-way valves aligned parallel to the joining surfaces are arranged in a common plane.
- the cuboid design of the 2/2 -way valves ensures particularly good space utilization.
- the rectangular shape of the 2/2-way valves promotes separate replaceability of each of the 2/2-way valves, without the need for disassembly of adjacent valve modules.
- the actuating means have a, preferably U-shaped, return device with a plurality of legs, which are connected to one another at one end by means of a connecting web, are each partially covered by coil means and are aligned perpendicular to the component surface.
- the actuation force necessary for actuating the valve member is provided by the at least two coil means, which are in each case electrically controllable magnet coils.
