Valve modules
Valve modules are pneumatic components that may be compared to terminals / modules.
They are passive bus participants which integrate (and combine) the function of digital output in a
pneumatic version. The valve modules are supplied with fluid through channels in the pneumatic block. On
actuation of the valves, the fluid is switched to the service ports via branch channels. Exhausting takes
place via the collective ports of the supply modules.
It has been expedient to integrate several valve modules in one housing. At the moment, 2 and 8-fold
versions are available.
Composition of the valve modules
The modular design enables a multitude of variants. The valve modules consist of:
