Model AS6 is a heavy-duty, quarter-turn rotary spring return actuator designed for industrial valve and damper automation, providing fail-safe operation upon power loss. It delivers a start torque of 800 in-lb (90.4 Nm) and an end torque of 600 in-lb (67.8 Nm), with a 12-second electric 90° cycle time and a 2-second spring return cycle time. The actuator features a permanent split capacitor motor with thermal overload protection, a power-on brake, and snap-action SPDT limit switches rated at 15A at 250Vac. It mounts to ISO 5211 F07 with a 0.66" square male drive and is rated NEMA 4, with optional NEMA 4X, 7, and 9 enclosures. Weight is 68 lb (30.8 kg). The duty cycle is 25%, with a maximum of 25 cycles per day. Operation is limited to -40°F to 150°F without additional heating.
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 lb·in.
Standard equipment includes 115Vac-1ph Continuous duty motor with thermal over load 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.
