Attachment to the control valve – Mounting parts and accessories
6. Insert the formed seal (17.1) into the
turnboard (17) and mount the turnboard
to the adapter block (13) using the
screws (17.2).
7. Mount the blank plate (18) to the turn-
board using the screws (18.1). Make
sure that the seals are correctly seated.
Note
A solenoid valve can also be mounted in
place of the blank plate (18). The orientation
of the turnboard (17) determines the mount-
ing position of the solenoid valve. Alterna-
tively, a restrictor plate can be mounted
(u AB 11).

NAMUR connection block using the
screws (13.1).
9. Insert the vent plug into the Exh. connec-
tion.
10. Place the positioner on the adapter block
(13) in such a manner that the follower
pin (2) rests on the top of the follower
plate (3, 3.1). Adjust the lever (1) corre-
spondingly.
Fasten the positioner to the adapter block
(13) using the two fastening screws (6.3).
Make sure the formed seal (6.2) is prop-
erly seated.

purging, connect the Y1 port of the
adapter block to the signal pressure con-
nection of the actuator. Seal the Y2 port
with a blanking plug.

For double-acting actuators and actua-
tors with air purging, connect the Y2
port of the adapter block to the signal
pressure connection of the second actua-
tor chamber or spring chamber of the
actuator.
