2 Safety
2.1 Safety instructions
–Only use the product in its original condition without unauthorised modifica-
tions.
–Only use the product if it is in perfect technical condition.
–Take into account 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.

lator, read the manual 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 product may generate high frequency interference, which may require inter-
ference suppression measures in residential areas.
2.3 Training of qualified personnel
Work on the product may only be carried out by qualified personnel who can

4 Product overview
4.1 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 Assembly
6.1 Assembly
6.1.1 Linkage 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.
3. Connect the valves on the underside using socket head screws and square
nuts. Tightening torque: 1.2 ± 0.2 Nm
4. Connect valves at the rear using socket head screws and square nuts. Tight-
ening torque: 1.2 ± 0.2 Nm

6.1.2 Creating pressure zones
For separating pressure zones, 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.
• 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.
6.2 Mounting

6.3 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.
7 Installation
7.1 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.
7.2 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 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 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 % of the setpoint value corresponds to 0 bar and 100 % of the setpoint
value corresponds to –1 bar.

interpreted as the lowest input value in order to suppress noise at the input signal

may be a special response in this area è Tab. 12 Zero point suppression.
