Conversion
The following conversion work can be undertaken on the valve terminal:
– Conversion to internal or external pilot air supply
– Addition of pressure zones
– Addition of valve positions (manifold sub-bases)
– Addition of supply plates for pneumatic auxiliary power supply
Shortening the valve terminal
Shortening the valve terminal by individual valve positions is only possible if the tie rod system is con
structed from individual extension pieces (

Information on permitted possible combinations of components and accessories can be
found in the Festo Catalogue (

7.1
Tie rod system
The mechanical connection between the modules of the valve terminal is achieved via a tie rod system
in the manifold sub-base, supply and end plates.
Design
The tie rod system of the valve terminal consists mainly of three parts:
– Threaded rod with lug for spanner, size 5
– Threaded sleeve with internal hexagon socket, size 4
– Tie rod screw with external hexagon, size 6
In addition, there is another extension piece to enable subsequent extension of the valve terminal.
