'''Quarter Turn Actuator''' is a device used for moving or controlling a mechanism or system that takes energy, usually created by air, electricity, or liquid, and converts that into some kind of motion. Quarter turn actuators are prepared with dry powder coating aluminum alloy. Quarter turn actuators are prepared with extended duty cycle induction motor. Quarter turn actuators are builded in thermal protection that prevents motor burning out. High alloy lubricated steel gear trains used in quarter turn actuator provides self locking function to avoid valve back drive. The quarter turn actuator is a rack and pinion combination that converts the linear movement of the shaft. Quarter turn actuators based on this principle exhibit an identical torque characteristic across the entire rotation angle range of 90°. | |||
