In the context of the AirLINE Ex 8650 pneumatic valve block, every assembly comprising terminal module, function module and pneumatic module is referred to as "slice".

A valve slice comprises the terminal module with the permanent wiring, equipped with an electronic basic module and a pneumatic basic module. The valves are then mounted on the basic module.

Design of a valve slice (terminal module on left, electronic basic module at top, pneumatic basic module at bottom, valves)

The valves and their electronic modules have intrinsically safe design (Ex i). For servicing purposes, they can be replaced during ongoing operation. They are easy to install and remove from the front.

The AirLINE Ex 8650 pneumatic valve block is supplied with compressed air via pneumatic connection washers, and the exhaust air is also discharged in this manner. A connection washer on each side terminates the pneumatic backplane on the left and right to the modules of the ET 200iSP. Valve slices for the two available air supplies of 300 l/min and 700 l/min can be mixed in between as desired.

Depending on the configuration, smaller supply elements can be produced using further pneumatic connection washers for intermediate supply. In this way it is possible to work with different pressures or to completely depressurized certain areas of the valve terminal in safety-related applications.

A configurator from BГјrkert Fluid Control Systems can help you in the selection and combination of components. It will provide you with:
