Disassembling the valve system
1. Make sure that the system is not under pressure or voltage and remove
all electrical and pneumatic connections.
2. Remove the valve system from the mounting surface.
Installing AV-EP base plates in the valve system
Damage to the contacts and the circuit board!
Removing the end plate on the valve system can separate the electrical contacts
to the valves in the valve system. A closing up of the valve system components
when tightening the end plate will result in damage to the separated contacts!
O Remove all directional valves and pressure regulators in the valve system
from the base plate before unscrewing the end plate on the valve system.
O Only mount the directional valves and pressure regulators on the base plates
after the valve system has been reassembled with the end plates.
Damage to the contacts and the conductors!
Touching the contacts and conductors can lead to damage and corrosion of the
circuit board.
O Take care when handling the circuit board that the contacts and conductors
are not touched.
O Preferably, wear gloves.
Take note that the two valve system series differ in the number of the fitted
tie rods! The AV03 valve system is held together with one tie rod. The AV05
valve system is held together with two tie rods. Expansions with an AV03-EP
therefore require one tie rod extension. Expansions with an AV05-EP require
two tie rod extensions. The figures for the following description refer to the
AV05-EP series. For the AV03-EP series, the process works in the same way,
but with only one tie rod.

Fig. 13: Removing valves and base plates
1. Remove all valves (Torx 8) from the valve system base plates.
2. Remove the IP protection cap.
3. Remove the hex socket-head screw (M4, wrench size 3): one screw
for the AV03-EP; two screws for the AV05-EP.
4. Remove the right end plate from the valve system.
5. Unplug the end plug from the last circuit board.
6. If necessary, remove base plates, along with the associated circuit boards,
until the desired installation valve position has been reached.

Installing the AV-EP base plate
Improperly tightened tie rods!
Incompletely or improperly tightened tie rods will damage the system.
O Before assembling the valve system, check whether the tie rod extensions
have been completely screwed in.
Only use original parts from AVENTICS. The tie rod extensions are adjusted
to the expansion coefficient of the base plates so that the valve system
remains leaktight under all operating conditions.
Fig. 14: Installing the AV-EP base plate
To assemble an AV-EP base plate:
1. Screw the tie rod extension (one for AV03-EP; two for AV05-EP) into the end
of the tie rod by hand until it hits the stop.
2. Insert the supplied circuit board into the circuit board on the valve system.
– Make sure the contacts on the circuit board contact safely and correctly.
3. Slide the AV-EP base plate onto the tie rod extension (one for AV03-EP;
two for AV05-EP).
– Make sure the seals have been inserted correctly on the base plates
and supply plates.
Re-assembling the valve system

Fig. 15: Re-assembling the valve system
1. If necessary, slide the circuit boards removed from the switching valves
onto the circuit board of the AV-EP pressure regulator.
2. If necessary, slide the removed base plates onto the tie rods with
tie rod extension.
3. Plug the end plug into the circuit board.
4. Place the end plate.
5. Retighten the hex socket-head screw (one screw for AV03-EP; two screws
for AV05-EP).
6. Replace the IP protective cap.
7. Reassemble all valves on the valve system base plates.
