global brand of quality electric actuators from 35Nm to 4500Nm


Options for Sun Yeh Actuators Series  

Options for the S series of mechanical spring return actuators include primarily the manual override gearbox system and modulating controller. Other options include heater and additional switches but these are included as standard in our offering. ATEX is also an option but we have listed this as a separate product range for ATEX OM series and ATEX S Series.

See selectable options below - both options, as are the the actuators themselves, are factory lead time and factory fitted only.
