ESA.EMD Series – Electric multiturn actuators with worm gear (100 to 900 Nm)
Robust worm gears for precise control
The ESA.EMD Series electric multiturn actuators have been specially developed for demanding control tasks in process and valve automation. With their extremely robust worm gear, they cover a torque range from 100 to 900 Nm.
Modern field communication and intelligent diagnostics In addition to standard control modes (OPEN/CLOSE and analogue control), the actuators support modern fieldbus systems such as Modbus, Profibus and HART. Local operation is straightforward via the integrated LCD display or contactlessly via infrared parameterisation. Comprehensive diagnostic and ESD (Emergency Shutdown) functions guarantee maximum safety during operation.
