Creating pressure zones and
separating exhaust air
• With the VTSA, pressure zones
with different working
pressures can be easily
created
• A pressure zone can be created
by separating the internal
supply ducts between the
series manifolds using
appropriate duct separation
• Compressed air supply and
exhaust via the supply plate
• Free positioning of the supply
plates and separating seals in
the VTSA
• Channel separations
integrated ex works as per the
order, differences can be
indicated via the coding
system for assembled valve
terminals
VTSA with CPX terminal
connection
• Up to 16 pressure zones
possible with VTSA
(if only size 1, ISO 5599-2,
is used, up to 32 pressure
zones are possible)
Further examples of pressure
supply and pilot air via an
end plate
• Internal pilot air, ducted
exhaust air/silencer
• External pilot air,
silencer/ducted exhaust air
Reliable exhausting of valves
or pressure zones
If used together with the MS6-SV
valve, certain areas can be
exhausted safely whilst the
pressure is retained for specific
valves or pressure zones.
This is a common requirement
for protective circuits.
Pressure zones for valve terminal type 44 VTSA
The illustration shows an example
of how three pressure zones are
built up and connected with duct
separation, with internal pilot air.
