The MODACT® MTN actuators are used for remote two-position or three-position control of the valves by a reverse rectilinear motion. The MODACT® MTN CONTROL actuators are fitted with an electronic position controller. In association with the valve exhibiting a suitable control characteristic, they form a position servo-loop. The output pull-rod of these actuators is automatically brought into a position corresponding to the input signal value of the controller.
