FasTrak is a high-capacity, high-precision digital-pneumatic valve controller that replaces a conventional positioner. It has an excellent dynamic performance and high flow (Cv = 2). Configuration and calibration is carried out with a HARTTM device or by self-calibration. FasTrak is compatible with double and single acting actuators, with or without a spring, a piston or a diaphragm.
