Attachment to the control valve – Mounting parts and accessories
4.5.3
Heavy-duty version
−
Required mounting parts and accesso-
ries: Table 5
Both mounting kits contain all the necessary
mounting parts. The parts for the actuator
size used must be selected from the mount-
ing kit.
Prepare actuator, and mount required
adapter supplied by the actuator manufac-
turer, if necessary.
1.
Mount the housing (10) onto the rotary
actuator. In case of VDI/VDE attachment,
place spacers (11) underneath, if neces-
sary.
2. For
SAMSON Type 3278 and VETEC
S160 Rotary Actuators
, screw the adapt-
er (5) onto the free end of the shaft or
place adapter (5.1) onto the shaft of the
VETEC R Actuator
. Place adapter (3) on-
to
Type 3278, VETEC S160 and VETEC R
Actuators
. For VDI/VDE version, this step
depends on the actuator size.
3.
Stick adhesive label (4.3) onto the cou-
pling in such a manner that the yellow
part of the sticker is visible in the window
of the housing when the valve is OPEN.
Adhesive labels with explanatory sym-
bols are enclosed and can be stuck on
the housing, if required.
4.
Fasten coupling (4) on the slotted actua-
tor shaft or adapter (3) using screw (4.1)
and disk spring (4.2).
5. Unscrew the standard follower pin (2)
from the positioner's M lever (1).
Attach the follower pin (Ø 5 mm) includ-
ed in the mounting kit to pin position
90°.
6.
Mount connecting plate (6) for required
G ¼ connecting thread or pressure
gauge bracket (7) with pressure gauges
on the positioner, making sure the two
seals (6.1) are seated properly. Double-
acting springless rotary actuators require
the use of a reversing amplifier on the
connection side of the positioner housing
(refer to section 4.6).
7. For actuators with a volume of less than
300 cm³, fit the restriction (order no.
1400-6964) into the signal pressure out-
put of the positioner (or the output of the
pressure gauge bracket or connecting
plate).
8.
Place positioner on housing (10) and
screw it tight. Taking the actuator's direc-
tion of rotation into account, adjust lever
(1) so that it engages in the correct slot
with its follower pin (Fig. 12).
