FasTrak Smart Digital Valve Positioner
High-capacity digital-pneumatic positioner with advanced control and HART™ communication.
High-speed valve control with self-calibration.
IP66-rated housing for harsh environments.
HART™ communication for advanced diagnostics.
The FT FasTrak is a high-precision digital-pneumatic valve positioner designed for industrial automation. It replaces conventional positioners, delivering high flow (Cv = 2) and fast, accurate control. Configurable via HART™ communication or self-calibration, it is compatible with single and double-acting actuators. Its robust IP66-rated housing and exhaust protection make it suitable for harsh environments, including extreme temperatures and high humidity. The FT features integrated position feedback, digital inputs and outputs, and high-speed serial communication. With self-calibration, configurable control parameters, and an optional remote feedback sensor, it ensures optimal valve performance in oil and gas, power, and process industries.
