Model AS6 electric spring return actuator is a robust heavy-duty actuator recommended for systems requiring as many as 74 cycles per day (27,000 annually). AS6 has a spring end torque of 600 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 440 lbÂ·in.
Standard equipment includes 115Vac-1ph continuous duty motor with thermal overload protection, set to fail closed (CW rotation) upon loss of power, two limit switches, power on brake, stainless steel fasteners, 300 series stainless steel output drive, polyester powder coating.
