Datasheets

Multi-turn electric actuator for gate and globe valves and for quarter-turn valves fitted with a gearbox. The inverter-driven brushless motor allows speed adjustment from 12 to 120 rpm and soft start and stop ramps, protecting the valve and reducing water hammer in the line.

Torque is measured directly at the motor and internal sensors monitor temperature, vibration and humidity; a data logger records torque profiles, PST curves, events and alarms for maintenance. Set-up is done without opening the actuator, from the local display and buttons or via Bluetooth.

Features

Five sizes from 32 to 500 Nm, ISO F10 and F14 flanges
Three-phase 400–480 V, 50/60 Hz supply with phase-loss protection
4 reconfigurable contacts, monitor relay and 4–20 mA output as standard
Profibus DP and Modbus RTU on request
Direct-drive handwheel, independent of the motor drive train
IP66/IP68 enclosure, −20 to +70 °C; explosion-proof version on request
