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 actuators SGM are rated for class A and B or types of duty S2 - 15 min, the actuators SGMR for class C or types of duty S4 - 40%.
Once power supply has been established, actuators equipped with integral controls can be operated via the operation elements on the local controls. The controls are perfectly adapted to the actuator.
The actuator can be completely set locally, without requiring direct connection to the DCS. Only operation commands and feedback signals are exchanged between the control system and the actuator. Motor switching is performed within the device and virtually without delay.
AUMA actuators are available with AM or AC integral controls.
