ESCRIPTION
Number of valve locations per module
Because of optimization for lower granularity, cost savings, design of valve units and loading of the
electronics, modules with different numbers of valve locations make sense. (see table)
Types of service port
The customer decides the optimal type for his needs - whether rapid coupling or threaded.
Add-on dimension
Larger valves require the basic modules to be wider. This allows a higher flow rate to be obtained. At the
present, the following add-on dimensions exist:
BASIC PNEUMATIC MODULE
Example of a basic pneumatic module
(type MP 11/2-fold)
General description
On the basic pneumatic module are to be found the
service ports for subsequent applications. Several
basic modules may be built up in a row by interlocking.
Sealing from the outside is maintained. By unsing a
bulkhead fitting, the P port may be sealed. Thus diffe-
rent working pressures can coexist in one valve block.
Variants
The different variants differ in the add-on dimension,
number of valve locations, connection configuration of
the valves, types of service port and the optional use
of non-return valves.
Not all possible variants are realized.
Non-return valve for exhaust ports
Since functionality with non-return valves is required for certain applications,
there are corresponding versions for this purpose.
• Without non-return valve
• Non-return valve in R
• Non-return valve in R+S
• For the module MP11, an integral pressure shut-off is additionally
available (for a technical description, see the next page)
* Special version 3-fold
with 10 mm valves
