The "small" electric part-turn actuator range with integral controls. All parameters are directly set at the actuator. The controls contain switchgear, power supply unit, interface to the DCS. The controls automatically switch 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 seawater even over a longer time period.
The SGM actuators are designed for open-close duty and positioning duty (classes A and B) / (short-time duty S2 - 15 min), the SGMR actuators for modulating duty (class C) S4 - 40%.
