2.1 Purpose
The valve terminal is based on a modular structure and creates the following connections:
– Common ducts for supply and exhaust air
– Electrical connections for supply and communication between all solenoid coils
Working lines (2) and (4) are provided for each valve position on the individual sub-bases. The valves
are supplied with compressed air (operating pressure and pilot pressure) via the common ducts and
connections in the supply modules. The exhaust air (from the valves and the pilot exhaust) is also ex­
hausted via these common ducts and connections.
The valve terminal can be supplemented by additional supply modules, e.g. to supply pressure zones.
The functional scope of a valve position can be extended by vertical stacking, e.g. for pressure regulation.
Depending on the types of valve used, the following valve terminal operating modes can be used:
– Standard operation with one or more pressure zones
– Reversible operation with compressed air supply via connections (3), (5) and exhaust via port (1)
– Low-pressure operation at 0 ... 3 bar
