Description
Reversing actuators are used for the positioning of flow control valves, butterfly valves, dampers, or any application requiring rotary motion. The actuators are available with up to six internal, easily adjustable switches.
A selection of exchangeable circuit boards provides a variety of functions including auto/manual selector switch, manual forward/reverse toggle switch, zero and span adjustment, parallel or master/slave operation, split range control, input signal override and selectable electronic linearization.
It is engineered for precision. It is particularly well suited for applications requiring a high degree of modulating accuracy and repeatability. The actuator may be mounted in any position. A selection of mounting brackets and shafts provides installation flexibility and allows for the simple replacement of most competitive actuators.
