Ap motronix manufactures electric actuators [type dec-1700] that are designed to meet the requirement of damper control, valve control applications where they are generally required to drive the load through less than one complete revolution in any direction and to stop instantaneously at any point of the stroke. Such devices also called as modulating motors, are extensively used for air-conditioning, boiler applications. These electric actuators consist of a reversible servomotor connected to the output shaft of the device through a series of precision hobbed gears. The great trains are sealed with high grade and high temperature stable grease, thereby ensuring permanent lubrication. Cam operated limit switches stop rotation of the output shaft at predetermined cw and ccw limit of travel.
