1.1 The VTSA/VTSA-F valve terminal
Festo supports your automation tasks at machine level with
theVTSA/VTSA-Fvalveterminals.Themodularstructureof
the valve terminal enables you to optimally customise it to
your machine or system.
The valve terminal pneumatics establish the following con-
nection:
– common ducts for supply and exhaust air
– electric signals of all solenoid coils.
The working ports (2) and (4) are provided for each valve
position on the individual manifold sub-bases. The valves are
supplied with compressed air (operating pressure and pilot
pressure) via the common channels and connections in the
pneumatic supply plates. The exhaust air (from the valves
and the pilot exhaust) is also exhausted via these common
channels and connections.
Dependent on its width, the valve terminal can be supplemen-
ted by additional pneumatic supply plates, such as to supply
pressure zones.
The function range at each valve position can be extended by
means of additional vertical stacking components, e.g. ex-
haust air flow control or pressure regulation.
Versions The valve terminal is available in a VTSA and VTSA-F design.
The VTSA-F valve terminal provides the mounted valves with
a higher flow volume.
