Model ASC12

Model ASC12 electric spring return actuator is a robust heavy-duty actuator recommended for systems requiring as many as 18 cycles per day (approximately 6,500 annually). The ASC12 has a spring end torque of 1200 lb·in with a closing speed of 3 sec./90 degrees upon loss of power. This actuator is ideally suited for ball valves and dampers with torque ratings of up to 900 lb·in.

Standard equipment includes 115Vac, 50Hz - 60Hz, 1ph continuous duty motor, two limit switches, a clutch, stainless steel fasteners, a 300 series stainless steel output drive and polyester powder coating.

This electric spring return actuator also comes standard with thermal overload protection and is set to fail closed (via counter-clockwise rotation) upon loss of power.
