Auma Part-turn actuators SGM 04.1 – SGM 12.1

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 components are made of bronze, all external screws are made of stainless steel. This ensures complete resistance against sea water even over a longer time period.

The modulating actuators of the SGM range are rated for intermittent duty S4 - 40%.

• Torque range from 25 Nm to 500 Nm
• Swing angles 82 ° to 98 °
• Operating times for 90° from 4 s to 90 s
• Limit and torque seating
• Variable speed, brushless motor
• Handwheel for manual operation

Ambient conditions:

• High enclosure protection
• High quality corrosion protection
