1. Overview of components
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 connection:
– 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 supplemented 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. exhaust 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.

If only manifold sub-bases that support the control of two
solenoid coils per valve position are used, any type of valve
can be placed in any valve position.
If, on the other hand, only manifold sub-bases that control
only one solenoid coil per valve position are used, the valve

entire valve terminal (also across pressure zones) through the
soft-start valve or the various right end plate variants. The
following applies:
– the valve terminal is always supplied with internal pilot air
through the soft-start valve
– you can choose whether the valve terminal should be
supplied with internal or external pilot air via the corresponding right end plate variants.

– For end plates with axial ports, the type of pilot air supply
(internal or external) is determined by the design.
– The following can be selected for the selector-end plate:
– the type of pilot air supply (internal or external)
– the manner of venting the pilot exhaust air (via
duct (12) or at the valve).
You can ascertain the end plate with which your VTSA/VTSA-F
valve terminal is fitted by means of the following table. Conversion b etween internal and external pilot air supply is described in section 5.6.2.

1.2.5 Pressure zone separation
Using special seal plates, you can divide the VTSA/VTSA-F
valve terminal into pressure zones ( 3.8). The following
ducts can be separated with the seal plates:
– supply duct (1) only
– supply duct (1) and exhaust ducts (3) and (5)
– exhaust ducts (3) and (5) only.
In the VTSA/VTSA-F valve terminal, the pilot control for the
valves is supplied with pilot air centrally via the right end
plate or via the soft-start valve. A pressure zone separation of
pilot ducts (12) and (14) is therefore not possible.
The number and type of pressure zones of your valve terminal
can be identified via the inscription on the manifold subbases ( Tab. 1/9). Alternatively, the pressure zones can also
be identified via the markings on the seal plates ( Fig. 1/4).

1. Overview of components
The vertical stacking components on the VTSA/VTSA-F valve
terminal are marked by type codes. The code is printed on
the side of the component. An identifier within the type code
indicates the function of the component; for example, in the
type code VABF-S4-1R1C2-C-10:
– identification R1 means the component is a P-pressure
regulator
– identification 10 means the control range of the pressure
regulator extends to 10 bar.
In the sales documentation and in the Festo Configurator, the
components are marked with an ID code.
You can identify the vertical stacking components with the aid
of the following table. Not every pressure regulator function
is available for all widths.
Note
•
Use a maximum of one vertical stacking component per
valve position if vibration and shock of severity level 2 is
expected ( Tab. A/4).

1.2.7 Pressure regulator plates
Mode of operation To influence the force of connected actuators, a pressure reg-
ulator plate with adjustable pressure regulating valve can be
built in between the manifold sub-base and valve. This pressure regulating valve maintains an essentially constant output pressure (secondary side) independent of supply pressure (primary side) and air consumption.
The following descriptions of the pressure regulator functions
are provided using the example of the pressure regulator
VABF-S4-1…C2-C-... (VTSA pressure regulator of
width 18 ...52 mm).
P-pressure regulator (identifier R1-...-6
and R1-...-10)
Pressurizing process The P-pressure regulator regulates the pressure in front of
the valve in duct (1) (P). This provides the same regulated
working air pressure in channels (2) and (4).
Exhaust process: The exhaust flow in the valve is from channel (2) to chan-
nel (3) and from channel (4) to channel (5).
Festo P.BE-VTSA-44-EN en 1312h Engl ish
1-23
1. Overview of components
The advantages of this pressure regulator are:
– The pressure regulator is not affected by exhausting,
since the pressure is regulated upstream of the valve.
– The pressure regulator can be adjusted at any time, as
the operating pressure is always present.
Application example:
– An equal output pressure is required at ports (2) and (4).
– A lower air pressure (e.g. 3 bar) is required than the oper-
ating pressure present at the valve terminal (e.g. 8 bar).
AB-pressure regulator (identifier R4-...-6
and R4-...-10)
Pressurizing process The AB-pressure regulator regulates the air pressure in
ducts (4) (A) and (2) (B) after the pressure medium has
passed through the valve.
Exhaust process During the exhaust process, the exhaust flows in the valve
unregulated from duct (2) to duct (3) and from duct (4) to
duct (5) via the pressure regulator.
1-24
Restrictions:
– The exhaust flow is restricted by the pressure regulating
valve.
– The pressure regulator cannot be adjusted in the exhaust
position. For example, the pressure regulator for duct (4)
cannot be adjusted when the valve is pressurised in the
switching position from duct (1) to duct (2) and vented
from duct (4) to duct (5).
Festo P.BE-VTSA-44 -EN en 1312h English
1. Overview of components
Application examples:
– If two different working pressures are required at
ports (2) and (4) instead of the operating pressure of the
valve terminal.
– If the reversible pressure regulating valve cannot be used.
For example, when 2x2/2-way valves or 2x3/2-way valves
with ducted solenoid exhaust (82/84) or when a flow control plate is used.
Fig. 1/5 shows the following switching position of the B-pressure regulator:
The working air is passed from duct (1) through the intermediate plate and the valve to the B-pressure regulator, where it
is regulated and then passed to port (2) of the manifold subbase. The exhaust is passed via duct (4) to pressure regulating valve A and then via the valve to duct (5).

Pressurizing process With the reversible pressure regulator, the air (duct (1)) is
split and routed directly to both pressure regulators. In each
case the regulated air is present in ducts (3) and (5) on the
valve. The valve is thus operated in reversible mode
( Fig. 1/6). This means:

1. Overview of components
Exhaust process Venting occurs in the valve from duct (4) or duct (2) to
duct (1) and in the intermediate plate guided to duct (5) or
duct (3) in the manifold sub-base.
Advantages compared with the AB-pressure regulator:
– Faster cycle times.
– 50 % higher exhaust flow rate, as air is not vented via the
pressure regulator. The load on the pressure regulator is
also reduced.
– No quick exhaust valves are required. The exhaust is duc-
ted completely via the valve terminal.
– Operating pressure is always present at the pressure reg-
ulator, as the pressure is regulated upstream of the valve.
In other words, the regulator can always be adjusted. In
the case of the AB-pressure regulator, the valve must
switch for this.
Festo P.BE-VTSA-44-EN en 1312h Engl ish
1-27
1. Overview of components
Disadvantages compared with the AB-pressure regulator:
– No use of 2x2/2-way valves (Ident. Code: CV, VV) and
2x3/2-way valves (Ident. Code: K, H, N) is possible in combination with ducted solenoid exhaust (82/84), as reversible pressure is present at the valve interface.
– No practical combination with an intermediate throttle
plate possible.
Application examples:
– When, instead of the operating pressure of the valve ter-
minal, two further different pressures are required in
ducts (2) and (4).
– When fast venting is required.
– When the pressure regulator must always be adjustable.

Flow control plate
This plate is used in vertical stacking for exhaust air flow control in ducts (3) and (5) in order to adjust the speed of the
corresponding actuator.
Vertical pressure shut-off plate
Note
The vertical pressure shut-off plates are only intended in
combination with VSVA valves from Festo. Duct 12 is not
blocked in the vertical pressure shut-off plate.
This plate can be used to cut off the corresponding valve in
vertical stacking from the terminal's operating and pilot pressure. Both duct (1) and duct (14) are shut off at the same
time. This means that the VSVA valve can be removed without
shutting off the pressure. When operating a valve terminal
with a vertical pressure shut-off plate, pay attention to the
instructions in section 3.4.2.
Vertical supply plate
This plate can be used to supply a valve in vertical stacking
with an individual operating pressure and pilot air supply
independently of the operating pressure of the terminal. The
internal pilot air is branched from duct (1) for this valve position.
1.2.8 Components for protective functions
Soft-start valves with piston position sensing
The purpose of the VABF-S6-1-P5A4-… soft-start valve (design
Appendix, Tab. B/6) is to slowly and safely build up the
supply pressure in duct (1) of the valve terminal or to quickly
vent duct (1).
1-30
Festo P.BE-VTSA-44 -EN en 1312h English
1. Overview of components
Fig. 1/7: Soft-start valve
The optimum pressure build-up and filling time required by
the application for each pressure zone is configured directly
on the valve terminal.
The VTSA/VTSA-F valve terminal can either be operated with
an internal pilot air supply via the soft-start valve or with an
internal or external pilot air supply via the different end
plates. The type of pilot air supply is determined by the seal
of the soft-start valve.
Festo P.BE-VTSA-44-EN en 1312h Engl ish
The soft-start valve is actuated electrically independently by
the multi-pin/fieldbus connection via a 4-pin plug (in accordance with ISO 15407-1) or separately via an optional M12
adapter.
Switch-on takes place in two stages:
– First the working pressure provided for duct (1) gradually
increases. The speed can be adjusted using a flow control
screw.
– Once the working pressure in duct (1) reaches a previ-
ously set value, the soft-start valve switches the full operating pressure at duct (1) of the valve terminal.
When the valve terminal is supplied with internal pilot air via
the soft-start valve, the full operating pressure is always
present at duct (14). This pressure causes the valves on the
valve terminal to immediately move to the required switching
1-31
1. Overview of components
position. When the valve is not switched, duct (1) of the valve
terminal is exhausted via the soft-start valve's exhaust port.
The switching point for full operating pressure is set to 4 bar
at the factory, but can be changed using an adjusting screw.
The piston position of the soft-start valve can optionally be
monitored by an inductive sensor (N/O contact). This sensor
registers whether the valve has switched and therefore
whether the valve terminal is being supplied with air. Due to
the required calibration, the later addition of the sensor by
the customer is not intended. A pressure gauge is optionally
available as a pressure indicator.
Note
– The VTSA/VTSA-F valve terminal can be equipped with a
maximum of 5 soft-start valves.
– If a soft-start valve is used in the VTSA/VTSA-F valve
terminal, no additional pressure-supplying components
may be used in the same pressure zone.
– Exhaust air cannot be expelled via the soft-start valve. If
a pressure zone is operated with a separate duct (1) and
3/5, an exhaust plate is required in this pressure zone.
– Instructions for combining the soft-start valve, pneumat-
ic supply plate and the right end plate can be found in
the assembly instructions for VABV-S6-1Q-....

1.2.9 Vacuum block VABF-S4-1-V2B1
The VABF-S4-1-V2B10 vacuum block is used to generate a
vacuum. The generated vacuum and a suction gripper produce a force which is used to grip and transport a workpiece.
The supply of compressed air for vacuum generation is controlled by an integrated solenoid valve. The vacuum is generated by actuating solenoid coil 12. The set reference value for
the generated vacuum is monitored via an integrated pressure sensor. Vacuum generation reverts to a self-holding
phase after reaching the set reference value. The vacuum
block controls the vacuum generation process independently
within the range of the set switching points (air-saving function). With the integrated solenoid valve, an ejector pulse is
activated and generated by activating coil 14 to release the
workpiece safely from the suction cup and to reduce the vacuum quickly. The length of the ejector pulse can be influenced by the duration of the electrical pulse. The strength of
the ejector pulse is influenced by the adjustable flow control
valve.

1.3.1 Valves
The following valve functions are available for the
VTSA/VTSA-F valve terminal in width 65 mm:
– 5/2-way valves, (monostable or bistable)
– 5/3-way mid-position valves.
Valves of width 65 mm (ISO 3) can be operated on the the
VTSA/VTSA-F valve terminal as follows:
– standard operation
– reversible operation
– low pressure
– vacuum.
Identifying the valves Valves of width 65 mm are identified by type code. The type
code is printed on the rear of the valve. An identifier within
thetypecodeindicatesthefunctionofthevalve.Forexample, identifier 5/2-...-FR inthetypecodeVL-5/2-D-3-FR-C
means that the valve is a monostable 5/2-way valve with
mechanical spring. You can identify the valve function with
the aid of the following table. In the sales documentation
and in the Festo Configurator the valves are marked with an
Ident. Code.

Tab. 1/15: Valve identification (width 65 mm)
1.3.2 Manifold sub-bases
The number of electrically controllable valve positions depends on the manifold sub-bases and the electrical connection used ( Tab. 1/2).
If only manifold sub-bases that support the control of two
solenoid coils per valve position are used, any type of valve
can be placed in any valve position.
1-38
If, on the other hand, only manifold sub-bases that control
only one solenoid coil per valve position are used, the valve
terminal can only be equipped with monostable 5/2-way
valves (Ident. Code M or O) or cover plates.

1.3.3 Pressure zones
The VTSA valve terminal of width 65 mm can be operated with
a maximum of 2 pressure zones. These pressure zones are
formed by isolating discs. These are inserted between the
manifold blocks in the supply duct (1) and, for special cases,
in the air exhaust ducts (3 or 5) as well. The first pressure
zone is supplied with compressed air via the adapter plate,
while the second pressure zone is supplied via the right end
plate.
1.3.4 Vertical stacking
You can mount further components at each valve position
between the manifold sub-base and the valve. These vertical
stackings enable you to implement certain additional functionsasdesired.

1. Overview of components
The vertical stacking components of width 65 mm are designated by a type code on the valve terminal. The code is printed on the side of the component. Identification within the
type code indicates the function of the components, e.g. type
code LR-ZP-A-D-3 indicates that this component is an A-pressure regulator. You can identify the vertical stacking components with the aid of the following table. In the sales documentation and in the Festo Configurator, the components are
marked with an ID code.

3.1 Compressed air preparation
Note
Unfiltered or incorrectly lubricated compressed air will
reduce the service life of the valve terminal.
•
Operate the VTSA/VTSA-F valve terminal as described in
the following two sections.
3.1.1 Operation with unlubricated compressed air
Note
Too much residual oil content in the compressed air will
reduce the service life of the valve terminal.
– When using bio-oils (oils that are based on synthetic
ester or native ester, e.g. rapeseed oil methyl ester), the
maximum residual oil content of 0.1 mg/m
be exceeded ( ISO 8573-1 class 2).
– When using mineral oils (e.g. HLP oils to DIN 51524 Part
1 to 3) or corresponding oils based on polyalphaolefin
(PAO), the maximum residual oil content of 5 mg/m
must not be exceeded ( ISO 8573-1 class 4).
This avoids operative malfunctions of the valves.

Excessive residual oil content is not permissible, independent
of the compressor oil, as otherwise the basic lubrication will
be washed out with time.

3. Installation
3.1.2 Operation with lubricated compressed air
Operate system equipment with unlubricated compressed air,
if possible. In this way, you protect the environment. Festo
pneumatic valves and actuators have been designed so that,
if used as intended, they will not require additional lubrication and will still achieve a long service life.
Note
The lifetime lubrication required for unlubricated operation
can be “flushed out” when products are operated using
lubricated compressed air.
If the system was commissioned with lubricated compressed air, a changeover to provisioning with unlubricated compressed air is not possible.
Note the following instructions if lubricated compressed air
must be used.
Festo P.BE-VTSA-44-EN en 1312h Engl ish
Note
The quality of compressed air downstream of the compressor must correspond to that of unlubricated compressed air.
•
If possible, do not operate all of your equipment with
lubricated compressed air.
•
If possible, always install the lubricators directly upstream of the consuming actuator.
3-5
3. Installation
Note
Incorrect supplemental oil and an oil rate in the compressed air that is too high will reduce the service life of
the valve terminal.
•
Use Festo special oil OFSW-32 or the alternatives listed
in the Festo catalogue (as per DIN 51524-HLP32, basic
viscosity 32 CST at 40 °C).
•
HLP 32 oils are to be used (according to ISO 8573-1,
5.3.2 or 5.3.5).
•
The additional lubrication must not exceed 25 mg/m³
(ISO 8573-1 class 5).
•
Check the correct lubricator setting ( following section).
This avoids operative malfunctions of the valves.
Setting the lubricator With the machine running (typical operating status):
– 0.2 to max. 1 drop/min.
or
–0.5to5drops/1000 l air.
Checking the setting The procedure described below can be used to check the
lubricator setting.
Note
Check the service units for condensate and lubricator setting twice per week.
1. Ascertain the actuator which is furthest from the lubricator.
2. Ascertain the valve terminal which controls this actuator .
3. Remove the silencer, if present, from the port (3/5).

4. Hold a piece of white cardboard at a distance of 10 cm
from the exhaust port.
5. Let the system run for some time.
6. Check the discolouration of the cardboard:
– There must be only a slight yellow colouring on the
cardboard.
– If oil droplets appear, this is an indication that too
much oil has been used.
Another indicator of over-lubrication is the coloration or
status of the exhaust air silencer:
– a distinctly yellow colouring of the filter element
– droplets of oil on the silencer indicate that the lubricator
setting is too high.
Festo P.BE-VTSA-44-EN en 1312h Engl ish
7. Correct any incorrect lubricator settings. If applicable,
take comprehensive maintenance measures of the compressed air supply into consideration.

3.2 General notes on connecting the tubing
Warning
Uncontrolled movement of the actuators, undefined
switching states and loose tubing lines.
This may result in personal injury or damage to property.
•
Switch off the operating and load voltage supplies
•
Switch off the compressed air supply
•
Exhaust the valve terminal pneumatics.
Note
Observe the following if the UL requirements are to be
complied with in your application:
– Rules for complying with the UL certification can be
found in the separate UL-specific special documentation.
The relevant technical data listed there also apply here.
– The technical data in this documentation may show val-
ues deviating from this.
Pleasenotethefollowing:
The components of the valve terminals contain electrostatically sensitive components. The components could be damaged if you touch the contact surfaces of the plug connectors
or if you do not observe the handling specifications for electrostatically sensitive devices.
Back pressure When exhausting large volume actuators or if the exhaust
performance is too small, back pressures can build up in the
valve terminal exhaust ducts. The back pressures can lead to
pneumatic actuation of other valves, especially with unswitched 3/2-directional control valves that are normally
closed.
3-8
Festo P.BE-VTSA-44 -EN en 1312h English
3. Installation
To avoid back pressures:
•
Optimise the pressurisation and ventilation capacity of
the valve terminal, for example, by using larger diameter
tubing or an additional compressed air supply via pneumatic supply plates with venting via a silencer or exhaust
plate.
•
Separate the exhaust ducts, if necessary, by using pressure zones ( Section 1.2.5).
3.2.1 Installing the tubing
If angled connectors or multiple distributors are used, the air
flow will usually be reduced.
Connection Proceed as follows:
1. Push the tubing as far as possible into or over the tube
coupling of the fitting.
Festo P.BE-VTSA-44-EN en 1312h Engl ish
2. Depending on connection:
– If necessary, pull the locking ring 1 over the tube
coupling ( Fig. 3/1).
– Tighten the clamping screw 2 ( Fig. 3/1).
– For the right end plate, size 2:
First mount the tubing at port (1) and then at ports (3)
and (5).
Secure the tubing with a hose clamp 3.
3. For better system clarity, bundle together the installed
tubes with:
– tubing straps or
– multiple hose holders.

3.3 Connecting the VTSA/VTSA-F valve terminal
To protect the working ports (2 and 4) from contamination,
seal unused valve positions (valve positions that are fitted
with cover plates) with blanking plugs or threaded blanking
plugs.
Note
In order to guarantee the optimum efficiency of the valve
terminal, we recommend in the following cases that more
than one supply or exhaust line be used:
– When large volume cylinders are operated at high
speeds
– When many valves are pressurised or exhausted simul-
taneously.
To do this, equip the VTSA/VTSA-F valve terminal with a
sufficient number of pneumatic air supply plates.
3.4 Pilot control, width 18 ... 52 mm
3.4.1 Venting pilot exhaust air
As per standard ISO 15407-2 and 5599-2, ports (12) and (14)
are intended for supplying the valve terminal with external
pilot air.
The Festo valves for the VTSA/VTSA-F valve terminal require a
pilot air supply exclusively via duct (14). In the case of the
reversible 2x3/2-way valves from Festo, additional operating
pressure is also required at duct (12) for the pneumatic
spring. This operating pressure must correspond to the pilot
pressure.
All other valves from Festo which are operated so they comply
with the ISO standard work independently of duct (12). The
pilot exhaust air is vented directly at each valve in an unducted manner.
Festo P.BE-VTSA-44-EN en 1312h Engl ish
3-13
3. Installation
The pilot exhaust air can also be vented via duct (12)
( Section 5.6.1). There should not be any pressure in the
duct (12) in this case, as this would prevent the valves from
switching.
Therefore, please observe the following points if you wish to
use duct (12) for venting the pilot exhaust air:
– The valve terminal is not equipped with reversible 2x2/2-
or 2x3/2-way valves.
– The valve terminal is not equipped with valves from other
manufacturers.
– The seals between the manifold sub-bases and the valves
must be mounted in the corresponding position
( Section 5.6.1).
– Valve terminals with a selector end plate must be oper-
ated in positions 3 or 4 of the selector plate ( Tab . 3/3).

3.4.2 Pilot air supply
Note
•
The VTSA/VTSA-F valve terminal can either be supplied
with internal pilot air via the VABF-S6-1-P5A4-... softstart valve or with internal or external pilot air via the
corresponding right end plate.
•
The port seal used for the soft-start valve determines
whether the internal pilot air is supplied via the soft-start
valveortherightendplate( Assembly instructions
VABV-S6-1Q-...). If the supply of internal p ilot air via the
soft-start valve is selected, there must be no other pilot
air supply feed (duct (14)) within the valve terminal.
Exhaust air cannot be expelled via the soft-start valve.
An exhaust plate is required for operation in a pressure
zone with separated ducts (1) and (3/5).
Internal pilot air supply If the operating pressure lies within the required pilot pres-
sure range for the valves ( Appendix A, Tab. A/5 and
Fig. A/1), you can operate the pilot control with an internally
branched pilot air supply. The pilot air is branched here from
supply duct (1).
Note
The internal pilot air supply is also branched centrally from
supply port (1) if the VTSA/VTSA-F valve terminal is
equipped with several pressure zones.
External pilot air supply If the operating pressure lies outside the required pilot pres-
sure range for the valves ( Appendix A, Tab. A/5 and
Fig. A/1), the pilot control must be supplied with external
pilot air. The pilot air is to be supplied via pilot port (14).
Festo P.BE-VTSA-44-EN en 1312h Engl ish

3. Installation
Note
•
External pilot air is supplied centrally via pilot port (14)
on the right end plate. This is the case even if the valve
terminal is operated with different pressure zones
( Fig. 3/5).
•
Set the pilot pressure according to the specifications in
Appendix A, Tab. A/5 or in the diagrams Fig. A/1.
•
Check which pilot variant your valve terminal has been
designed for ( Section 1.2.4 “Pilot control (pilot air supply)”).
•
Carry out the necessary installation procedures or settings in accordance with Tab. 3/1 and Tab . 3/2.
Note
Valve terminal with selector end plate:
Danger of damage to the selector plate.
To change the selector plate position, first remove the lock-
ing screw then pull the selector plate out of the guide in
the end plate before inserting the selector plate into the
new position.
Valve position with vertical pressure shut-off plate:
•
In this valve position, duct (14) is blocked by the vertical
pressure shut-off plate ( Appendix B, Tab. B/10). The
valve is supplied with pilot air internally branched from
duct (1). This is the case even if the valve terminal is
operated with external pilot air supply.
Valve terminal with selector end plate and vertical pressure shut-off plate:
•
The valve terminal may only be operated in positions 3
and 4 of the selector plate. Otherwise, pilot air 12 may
escape at the interface to the valve when the valve is
replaced and the pilot pressure could break down.
