Spring Return Actuators - 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 6500 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 over load protection and is set to fail closed (via counter-clockwise rotation) upon loss of power.
