Technical Features
COMPACT ELECTRIC ACTUATOR: HIGH TORQUE AND ADVANCED CONTROL – SERIES 50

On/Off
Standard Open/Close, power to open, power to close. Stays put on loss of power.
Failsafe/Modulating Failsafe
High Speed / Modulating High Speed
This actuator allows for fast opening and closing, with a runtime 50% faster than the standard, achieving 1 second in the 10, 20, and 50Nm series with a 24VDC motor. Additionally, it offers modulating control through 4-20mA, 0-10V, or 2-10V, enabling a movement from 4mA to 20mA in 1 second (only for the 10, 20, and 50 series with DC motor).
Smart Menu
All of our Smart actuators come with a SmartMenu featuring password-protected firmware. Once the password is entered, you can change parameters such as speed, working angle, failsafe position, 3-position configuration, and much more.
Timer
Through our SmartMenu, the Timer series allows programming a 24/7 timer with up to 60 operations (open/close movements) per day. Intelligent functionality without the need for a PLC.
Modbus
Modbus RS485/RTU and CANBus are available as standard to connect the actuator to a BUS system. Through the BUS communication protocol, you can read the actuator’s position, detect errors, and more. We also offer Modbus TCP/IP upon request.
Other protocols will be available soon.
Multi Turn
The Multi Turn series is designed for non-rising stem valves, such as diaphragm, gate, and knife valves. Through the SmartMenu, you can adjust the number of turns of the actuator according to the valve’s requirements. For more details, refer to the MT series data sheet.
Feedback
All of our actuators have open/close feedback. The basic models use mechanical switches, the Smart series uses electronic relays, and the modulating models have a modulation output (e.g., 4-20mA) instead of end-of-travel feedback.
3 Positions
Through the SmartMenu, you can configure the actuator in 3 positions (open, close, and intermediate) or set it to 0-90-180 degrees for 3-way valves. This flexibility allows precise adaptation of the actuator to various applications.
Local Control
Through the SmartMenu, the smart actuators allow manual operation via touch buttons on the screen. Protected by a password, it offers electronic manual override, facilitating opening and closing when power is available.
