AUMA SQ Electric Part-Turn Actuator
Product Overview
The AUMA SQ series is a range of electric part-turn (quarter-turn) actuators designed for open-close and positioning duty. These robust actuators are commonly used to automate butterfly valves, ball valves and plug valves. They feature reliable limit and torque sensing, a handwheel for manual operation, and high enclosure protection for demanding industrial environments.
