Product Q&A
Q: What are the primary applications for the STG 90-03 actuator? A: It is widely used in medium to large combustion engines, turbines, and industrial steam valves where precise electronic speed or position control is required.
Q: Does this actuator require an external linkage system? A: Yes, the STG 90-03 typically connects to the engine’s fuel system via a mechanical linkage, though its high torque capability allows it to drive most standard governor shafts directly.
Q: Is maintenance required for the internal motor components? A: Because it utilizes a brushless DC motor and permanent lubrication, the unit is largely maintenance-free under normal operating conditions, significantly reducing downtime compared to hydraulic alternatives.
