Quarter-Turn Actuators
Quarter-turn actuators move control valves at 90 degrees and move faster than linear actuators. With their compact and durable builds, they are ideal for heavy-duty applications that require added torque. Popular examples include:
Rack and pinion actuator: Converts linear movement into rotational movement for quarter-turn valves, such as butterfly, ball or plug valves. MSEC carries a selection of rack and pinion actuators from several brands, including world-renowned Limitorque®
Vane actuator: Features a cylindrical chamber containing the movable vane and the shaft on which the vane is mounted. Pressure applied on one side of the vane causes it to rotate and create motion. It is suitable for SIL-required and pipeline applications, like the refurbished actuators from SVC.
