Original: de
Proportional directional control valve VPWP
Warning
en Sudden uncontrolled movements of the actuators can cause injury to human
beings.
Before carrying out installation and/or maintenance work, switch off the
following sources of energy in the sequence specified:
• Compressed air supply
• Power supply
1 Use for intended purpose
Proportional directional control valve VPWP is intended to be used for controlling
and activating pneumatic drives with displacement encoders on an axis controller
or end-position controller from Festo (e.g. CPX-CMAX or CPX-CMPX). Example
application Fig. 1.
The device is intended for use in an industrial environment. In residential areas,
measures for radio interference suppression may have to be taken.

3 Assembly
When fitting to moving parts:
• Attach the VPWP perpendicular to the direction of movement. Acceleration
forces thus have no influence on the valve slide setting.

• Attach the VPWP as close to the drive as possible according to one of the
following alternatives (
– on an even surface with two M3
bolts and one retaining washer
each.
The tightening torque is
1.5 Nm ± 10 %.
