The "small" electric part-turn actuator range with integral controls.
All parameters are directly set at the actuator.
The controls contain switchgears, power supply unit, interface to the DCS. The component automatically switches the actuator off, once the valve end position is reached, motor overheating is detected or a torque overload has occurred.
All housing parts are made of aluminium. For this reason, the actuators are lightweight devices.
