Model AS6 is a heavy-duty, quarter-turn spring return actuator for fail-safe valve and damper automation, delivering 600 in-lb end torque and 800 in-lb start torque. It operates in 12 seconds electrically and returns in 2 seconds via spring, with a 25% duty cycle and 25 cycles per day limit. The motor is a permanent split capacitor type with thermal overload protection, rated for 115V, 208V, or 230V single-phase. It includes a power-on brake, snap-action SPDT limit switches (15A @ 250Vac), and a thermally bonded polyester powder coat. Mounting complies with ISO 5211 F07 with a 0.66" square drive. Weight is 68 lb (30.8 kg). Rated for -40°F to 150°F (-40°C to 65.6°C), it meets NEMA 4 standards with optional NEMA 4X, 7, and 9 enclosures.
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.
