10 Functional description
The GEMÜ 9468 is a motorized quarter turn actuator with
manual override and an optical position indicator. The hous-
ing is made from aluminium (actuator version
4100/4200/6400) or plastic (actuator version 2070). The mo-
tor and gearbox are combined in one housing. The actuator
has flexible electrical connections (connectors). The quarter
turn actuator is designed for use with AC or DC operating
voltages and utilises a DC motor with a secondary planetary
gear/toothed belt drive. The 90° movement is achieved by a
ball screw and lever based on the scotch yoke principle.
Optional accessories:
–
Additional adjustable limit switches for potential-free
control signals
–
Integrated positioner, 4–20 mA
–
Analogue position feedback via potentiometer
–
Suitable mating connectors are included and can be
reordered

10.1 Actuator versions
The following actuator versions are available:
2070: 70 Nm, transmission via a planetary gear and
–
toothed belt on a trapezoidal spindle
4100: 100 Nm, transmission via a planetary gear and
–
toothed belt on a trapezoidal spindle
4200: 200 Nm, transmission takes place via a planet-
–
ary gear and toothed belt on a ball bearing spindle
6400: 400 Nm, transmission takes place via a toothed
–
belt on a ball bearing spindle
This spindle and a lever can be used to implement a 93°
rotary movement. This pivoting movement is transmitted to
the shut-off valve via a hub.
10.2 Functional versions
The following functional versions are available:
00 – Relay version
OPEN/CLOSE control via remote change-over switch, with re-
lay, not reversible, one connector (overall height: 1).
0E – Two additional potential-free limit switches (relay ver-
sion)
For signal detection for indicator (e.g. signal lamp), with re-
lay, not reversible, two connectors. These two additional limit
switches can be adjusted by undoing two screws per switch
(overall height: 1).
0P – Potentiometer output (relay version)
Position feedback via potentiometer output, with relay, not
reversible, two connectors (overall height: 1).
A0 – Design
OPEN/CLOSE control via remote change-over switch, one
connector (overall height: 2).
AE – Two additional potential-free limit switches
For signal detection for indicator (e.g. signal lamp), two con-
nectors. These two additional limit switches can be adjusted
by undoing two screws per switch (overall height: 2).
AP – Potentiometer output
Position feedback via potentiometer output, two connectors
(overall height: 2).
E1 – Control module
Position control via integrated three-point controller with ex-
ternal set value specification 0–10 V
Two connectors (overall height: 2).
E2 – Control module
Position control via integrated three-point controller with ex-
ternal set value specification 0/4–20 mA
Two connectors (overall height: 2).
