Product Overview
The Air Torque AT101U S12 FC is a high-performance pneumatic actuator engineered for precise quarter-turn valve automation in demanding industrial process environments. Manufactured by Air Torque, a globally recognized specialist in rack-and-pinion pneumatic actuation technology, this model belongs to the AT series of double-acting and spring-return actuators. The AT101U S12 FC features a robust anodized aluminum body with a hard-anodized aluminum piston and a precision-machined rack-and-pinion mechanism that converts linear piston motion into a 90° rotary output torque. The “S12” designation indicates a specific spring-return configuration with a defined spring set, while “FC” denotes a fail-close (spring-to-close) action, ensuring the valve returns to a safe closed position upon loss of air supply. This actuator is designed for direct mounting to quarter-turn ball, butterfly, and plug valves via standard ISO 5211 interfaces, making it an essential component in automated process control loops, emergency shutdown systems, and industrial flow regulation applications.
