The quarter-turn pneumatic actuator is the most in-demand industrial automation component in Mexico: it operates ball and butterfly valves using compressed air in 1 to 5 seconds, with available torque ranging from 10 Nm for ½" ball valves to over 3,000 Nm for large-diameter butterfly valves, and a lifespan of millions of cycles without significant degradation. Its double-piston rack and pinion design converts air pressure into 90° rotational motion directly, reliably, and with low maintenance. At Cematic, we supply quarter-turn pneumatic actuators in single-acting and double-acting configurations, with a NAMUR interface for direct solenoid and limit switch mounting, and an ISO 5211 interface for universal compatibility with valves from all manufacturers.
