Model AS10 electric spring return actuator is a robust heavy-duty actuator recommended for systems requiring as many as 18 cycles per day (approximately 6500 annually). AS10 has a spring end torque of 1000 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 775 lb-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.


Spring return electric actuators from Indelac Controls Inc. (ICI) are specially designed for fail-safe applications using quarter-turn valves and dampers. Our spring return electric actuators are equipped with a hardened steel spur and helical gear drive train to guarantee reliable protection against catastrophic process failure during  of the electricity to the system. Internal components are permanently lubricated at our manufacturing facilities, ensuring high efficiencies between moving parts, minimal routine maintenance, and quiet operation throughout the life of the actuator.

All standard equipment is enclosed in a heavy-duty aluminum enclosure with a thermally bonded ultraviolet resistant polyester powder coating to comply with NEMA 4 requirements for protection against ingress of water, dust, and dirt. Optional enclosures are available to meet or exceed the NEMA 4X and NEMA 7 specifications for safe and efficient operation in corrosive, ignitable, or explosive environments. Epoxy coatings are available to protect against caustic wash-downs, additional coating options are available upon request.

To ensure compatibility with a wide range of applications, ICI’s spring return actuators are available in six different models with various specifications and end torque capabilities (up to a maximum of  pounds).

Unlike pneumatic spring return actuators, spring return electric actuators must be powered to the open position and powered to the closed position during  operation to maximize the life of the product. The spring return  functionality is for use during power failure only.

Our actuator units have been designed to provide accurate control and reliable fail-safe automation capabilities while also striking a balance between cost-effectiveness and durability.
