2 Safety
2.1 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.
– Prior to mounting, installation and maintenance work: Switch off power sup-
ply and secure it from being switched back on.
– Before changing any settings in the menu of the proportional-pressure regu-
lator, read the description of the product è 1 Applicable Documents.
2.2 Intended Use
The proportional-pressure regulator is intended to regulate a pressure propor-
tional to a specified setpoint value.
The device is intended for use in an industrial environment. Outside of industrial
environments,e.g. in commercial and mixed-residential areas, actions to sup-
press interference may have to be taken.
2.3 Training of skilled personnel
Installation, commissioning, maintenance and disassembly should only be con-
ducted by qualified personnel.
The specialized personnel must be familiar with the installation and operation of
electrical and pneumatic control systems.

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.

6 Transport and Storage
– Store the product in a dry, UV- and corrosion-protected environment.
– Ensure short storage times.
7 Mounting
7.1 Assembly
7.1.1 Linking of Valves
Up to 5 valves can be linked. The connecting kit VAME-P18-K-P5 is required for
linking 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 è Fig.2.
Fig. 2 Insert O-ring
3. Connect the valves on the underside using socket head screws and square
nuts. Tightening torque: 1.2±0.2Nm è Fig.3
Fig. 3 Fitting for valve underside
4. Connect valves at the rear using socket head screws and square nuts. Tight-
ening torque: 1.2±0.2Nm è Fig.4

7.1.2 Creating Pressure Zones
In the case of pressure zone separation, connect the compressed air supply to
both ends of the valve manifold.
For pressure zone separation, the plug screw can be left in duct (1) of the valve.
Plug screws for duct (1) can also be ordered as accessories (VAME-P18-BP-
G18-P5) èwww.festo.com/catalogue.
1. Screw the plug screw into the duct (1) of the selected valve è Fig.5. Screw in
the plug screw until it is flush with the surrounding surface.

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 leads to improved control precision and shorter 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 and Combined Vacuum / 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 SELV or PELV circuits that guarantee a reli-
able electric disconnection from the mains network.
• Observe IEC60204-1/EN60204-1.
1. If a screened cable is used: earth the shield at the cable end farther 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

1) The valve can be operated with 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) An active regulation only takes place from a setpoint value of 1% FS, below this the valve is in a zero
point suppression.
4) For variants VPPI -...- 1V0H -..., 0% of the setpoint value corresponds to 0bar and 100% of the setpoint
value corresponds to –1bar.
