4.1 General description
▪Electric actuator for the automation of a control valve
The electric actuators are used for actuating control valves in building services
systems and industrial plants.
Continuous-action actuator
EMV 211/145, EMV212/148, EMV212/144:
The electric actuator provides continuously variable actuation for control valves. The
input signal, the characteristic curve and the control value (voltage/current) can be
set via DIP switches. Continuously variable actuation enables variable volume flow
rate control or the control of different operating statuses, e.g. setback operation.
EMV213/145, EMV213/148:
The electric actuator provides continuously variable actuation for control valves.
Variable actuating times can be set via DIP switches. Continuously variable actuation
enables variable volume flow rate control or the control of different operating
statuses, e.g. setback operation.
3-point actuator
EMV211/146, EMV211/147, EMV212/148, EMV212/150, EMV212/146, EMV212/147:
The electrothermal actuator enables the automatic opening and closing of control
valves. For instance, the actuator can be controlled by a thermostat, so the room
temperature can be controlled by opening and closing the heating circuits or air-
conditioning circuits.
3-point part-turn actuator
EMV213/147, EMV213/150:
The electronic part-turn actuator enables the automatic opening and closing of
control valves. Variable actuating times can be set via DIP switches. For instance, the
actuators can be controlled by an ambient temperature thermostat, so the room
temperature can be controlled by opening and closing the heating circuits or air-
conditioning circuits.
Electrothermal actuator
EMV311:
The electrothermal actuator enables the automatic opening and closing of control
valves. For instance, the actuator can be controlled by a thermostat, so the room
temperature can be controlled by opening and closing the heating circuits or air-
conditioning circuits.
Electrothermal continuous-action actuator
EMV311/PRO:
The electrothermal continuous-action actuator enables the automatic opening and
closing of control valves as well as a continuously variable volume flow rate control
or the control of different operating statuses, such as setback operation during the
day or night.

4.5 Function
Electrothermal actuators
Function Electrothermal actuators contain a temperature-sensing material that expands when
voltage is applied. Its expansion causes a linear movement of the actuator stem
acting on the valve.
Electric linear actuators
Function Electric linear actuators are fitted with a gear unit that converts the rotary movement
of the integrated electric motor into a linear movement.
Electric part-turn actuators
Function Electric part-turn actuators are fitted with a gear unit that converts the rotary
movement of the integrated electric motor into a swivelling movement limited to
90°.
4.6 Noise characteristics
The sound pressure level depends on the local conditions and the operating point. It
is ≤ 30dB(A).
