justing screw (5b).

adjusting screw (5b) and lock the adjust-
ing screw with the lock nut.

both end positions. If necessary, repeat
the points 1 to 4. If you also want to
adjust the other end position, continue
with point 5.

If this is not already the case, allow the
actuator to swing into the open position

ator to the open position and vent the
actuator. If the setting needs to be cor-
rected again, repeat points 5 to 8.
7. Maintenance and re-
pair
The automatic valve is a maintenance-free
device.
In terms of operational safety, however, it is
recommended to check them for function
and to switch at least every three months
but no later than after 50,000 switching cy-
cles; and in case of difficult operating condi-
tions even more often.
Do not use harsh detergents or abrasives to
clean the housings.
7.1 Maintenance of rotary
actuator
In principle, it is possible to repair the pneu-
matic rotary actuator by replacing the seal
and wear parts sets.
7.2 Maintenance ball valve
Repair and maintenance of the seal and
wear parts of the butterfly valve must not be
carried out because it is about high-pres-
sure glued ball valve.
NOTE
We recommend that you have the repair
carried out by the company bar GmbH.
We will be pleased to offer you a corre-
sponding servicing, maintenance or re-
pair. Please contact the company bar
GmbH for this.
