Valvcon ADC-Series brushless DC electric actuators support continuous-duty operation with broad application adaptability, engineered to automate quarter-turn valves and dampers. Two enclosure rating options are provided: NEMA 4/4X, and NEMA 4/4X/7&9. The actuator comes standard with universal power and control circuitry, a holding brake and space heater. It holds CSA (C US) certification and CE marking; ATEX certification is available for WX versions that exclude battery backup.
