Technical data Multi-turn actuators
Features and functions
Type of duty
(Multi-turn actuators for open-
close duty)
Standard
Short-time duty S2 - 15 minutes, classes A and B
according to EN 15714-2. For nominal voltage and
104°F (40°C) ambient temperature and at load with
35% of the maximum torque.
Type of duty
(Multi-turn actuators modulating
duty)
Standard
Intermittent duty S4 - 25%, class C according to
EN 15714-2. For nominal voltage and 104°F (40°C)
ambient temperature and at modulating torque
load.
Motors
Standard
Single-phase AC motor with permanent split
capacitor (PSC), type IM B9 according to
IEC 60034-7, IC410 cooling procedure according
to IEC 60034-6.
Mains voltage, mains frequency
See the nameplate of actuator controls.
Permissible variation of mains voltage: ±10%
Permissible variation of mains frequency: ±5% (for
3-phase and single-phase AC current).
Overvoltage category
Category III according to IEC 60364-4-443
Insulation class
Standard
F, tropicalized
Motor protection
Standard
Option
Thermoswitches (NC)
DC motors: Without
PTC thermistors (according to DIN 44082)
PTC thermistors additionally require a suitable
tripping device in the actuator controls.
Self-locking
Self-locking: Output speeds up to 90 rpm (50 Hz),
108 rpm (60 Hz).
NOT self-locking: Output speeds from 125 rpm (50
Hz), 150 rpm (60 Hz)
Multi-turn actuators are self-locking, if the valve
position cannot be changed from standstill while
torque acts upon the output drive.
Motor heater
Standard
Voltages: 110 – 120 Vac, 220 – 240 Vac (3-phase
and single-phase AC motors)
Power depending on the size 12.5 – 25 W
Manual operation
Manual drive for setting and emergency operation,
handwheel does not rotate during electrical
operation.
Indication for manual operation
Option
Indication whether manual operation is active/not
active using a single switch (1 change-over
contact)
