2 Product labelling
–Observe the specifications on the product.
Warning symbol
The following warning symbol is on the product VPPI-...-S1BT:
Symbol Meaning
Mechanical overload can cause the valve to malfunction. Under certain circum-
stances, this malfunction will cause permanent energisation of the coils resulting in
a hot surface.

3 Safety
3.1 Safety instructions
–Only use the product in original status without unauthorised modifications.
–Only use the product if it is in perfect technical condition.
–Take into consideration the ambient conditions at the location of use.
–Before working on the product, switch off the power supply and secure it
against being switched on again.
–The product variants VPPI-...-A.../-V...-S1BT have a Bluetooth interface that is
permanently active. Fuse protection is therefore required.
3.2 Intended use
The proportional-pressure regulator is intended to regulate a pressure propor-
tional to a specified setpoint value.
The product may generate high frequency interference, which may require inter-
ference suppression measures in residential areas.
4 Additional information
–Contact the regional Festo contact if you have technical problems
è www.festo.com.

5 Product overview
5.1 Function
A built-in pressure sensor records the pressure at the working port and compares
this value with the setpoint value. In the event of deviations between the setpoint
value and actual value, the valve regulates until the outlet pressure has reached
the setpoint value.

7 Assembly
7.1 Assembly
7.1.1 Linkage of valves
Up to 5 valves can be linked. The connecting kit VAME-P18-K-P5 is required for the
linkage è www.festo.com/catalogue.
The connecting kit consists of 2 square nuts, 2 socket head screws and an O-ring.
1. Remove the plug screw and sealing material from the duct (1).
2. Insert the O-ring into the duct (1) between 2 valves.
3. Connect the valves on the bottom using socket head screws and square nuts.
Tightening torque: 1.2 ± 0.2 Nm

4. Connect the valves at the rear using socket head screws and square nuts.
Tightening torque: 1.2 ± 0.2 Nm
7.1.2 Creating pressure zones
For separating pressure zones, connect the compressed air supply to both ends of
the valve manifold.
The plug screw can be left in the duct (1) of the valve for pressure zone separa-
tion.
Plug screws VAME-P18-BP-G18-P5 for the duct (1) can also be ordered as accesso-
ries è www.festo.com/catalogue.
•Screw the plug screw into the duct (1) of the selected valve. Screw in the plug
screw until it is flush with the surrounding surface.
7.2 Mounting

Fig. 4: Individual valve
7.3 Mechanical installation
1. Make sure there is sufficient space for the connecting cable and tubing con-
nections.
ÄThis will prevent kinks from forming in the connecting cables and the
tubing.
2. Place the valve as close to the consumer as possible.
ÄThis improves control precision and reduces response times.
8 Installation
8.1 Pneumatic installation
Valves for standard operation (overpressure)
1. Attach the tubing to the connections:
–Compressed air (1)
–Working air (2)
2. Fit a silencer at the exhaust air connection (3) or provide for ducted exhaust
air.
Valves for vacuum operation or combined vacuum and overpressure operation
(VPPI-...-1V...H-...)
1. Attach the tubing to the connections:
–Vacuum (3)
–Working air (2)
2. Connect a compressed air supply to port (1) or mount a silencer to protect the
valve from coarse dirt particles.
8.2 Electrical installation
WARNING
Risk of Injury due to Electric Shock.
• For the electric power supply, use only PELV circuits that ensure a reliable
electric disconnection from the mains network.
•Observe IEC 60204-1/EN 60204-1.
• The unit must be powered by a power source that fulfils the requirements of an
energy-limited circuit in accordance with IEC 61010-1/EN 61010-1.
1. If a screened cable is used: earth the shield at the cable end away from the
valve.
2. Install electrical connecting cable without squeezing, kinking or stretching.
3. Tighten the electrical connecting cable onto plug M12. Tightening torque:
maximum 0.3 Nm

10.2 Fault Clearance
Error description Cause Remedy
Valve does not respond. Operating voltage not applied. Check the operating voltage
connection.
No setpoint voltage. Check the controller and con-
nection.
Working temperature is too
high. Valve is in temperature
shut-off.
Switch off the valve, let it cool
down and restart.
Reduce ambient temperature
and / or temperature of
medium.
Valve normally open:
The working pressure at (2)
falls to the level at (3) (ambient
pressure or vacuum).
Cable break setpoint input Check connection to setpoint
generator.
Replace supply cable.
Valve normally closed:
The working pressure at (2)
deviates upwards or down-
wards from the setpoint value
(working pressure is neither
pressurised nor exhausted).
Cable break setpoint input Check connection to setpoint
generator.
Replace supply cable.
Setpoint value not reached. Input pressure at (1) is too low. Increase input pressure at (1).
Maintain permissible maximum
operating pressure è 12 Tech-
nical data.

1) The valve can be operated at an input pressure within the specified range. It must be noted here that the
specified control quality is only fulfilled with a permanent supply within the operating pressure range and
that the control pressure can reach the maximum available input pressure.
2) The specified control quality is only achieved if there is a permanent operating pressure supply at the
valve within the specified range.
3) Active regulation is only from a setpoint value of 1% FS, below which the valve is at zero point suppres-
sion.
4) For variants VPPI-...-1V0H-... 0% corresponds to setpoint value 0 bar and 100% to setpoint value –1 bar.
