Modulating motors

Key Attributes.

The AR series of valve and damper actuators come in two sizes. These actuators drive the load through less than one complete revolution in both directions and stop instantaneously at any point of the stroke. With the addition of a worm gear system the actuators can be used to operate multi-turn valves. The position of the output shaft can be controlled with a 4-20mA controller. For feedback, the actuator is equipped with a potentiometer.
