Allen-Bradley QC16C Pneumatic Rotary Actuator

QC16C Pneumatic Rotary Actuator is an unbranded rotary pneumatic actuator commonly supplied as an OEM replacement component for valve automation and industrial motion control. It delivers 90° quarter-turn motion via a double-square output shaft and can be configured as double-acting or spring-return depending on the installation. The aluminum alloy body, ISO 5211 / NAMUR mounting compatibility, and operation on clean, dry compressed air at typically 40–120 psi provide reliable valve actuation in industrial environments. It is commonly used with ball valves, butterfly valves, and dampers in chemical processing, water treatment, food processing, and manufacturing settings, with common replacements including Festo DSR, SMC MSQB, and Air Torque AT series.
