The Turn-Force “TF Series” electric actuator is built to global design standards, including ISO 5211 mechanical transmission specifications. Operating voltages range from 12 vac/vdc to 575v 3 phase and torque range from 200 to 177,000 inch lbs, with an IP68 enclosure as STD. With an epicycle drive transmission, TF-Series actuators are available as on/off, proportional, fail-safe and with local control stations. Turn-Force also provides linear electric actuators.
