Quarter-turn electric actuators

Category Brand


The quarter-turn  electric actuators are provided with a base plate with multiple drilling and are available with a wide range of switch inserts that allow the direct coupling to most of the valves.

The quarter-turn electric actuators are equipped with a mechanical position indicator and provide an intelligent control unit for engine monitoring and internal temperature, in order to avoid any overheating problem.

The  quarter-turn electric actuators do not incur any condensation, thanks to an integrated part which is automatically activated when the temperature drops below 10 °C.

On the quarter-turn electric actuator an electric motor is installed with a universal power supply module. Thanks to its unique design, this module is able to adapt to any voltage from 24 to 240 V. Moreover, option boards for three-phase power are also supplied.

The  quarter-turn electric actuators are provided with suitable standards for ON/OFF and modulation services.

Thanks to their lightweight and compact design, the quarter-turn electric actuators are compact and easy to install on small valves.

Every quarter-turn electric actuator is provided with instructions on how to perform the manual emergency operation.
