The FasTrak FT D00ASSA is a high-performance model from the FasTrak FT series (manufactured by IMI STI, Italy), a smart digital-pneumatic valve positioner/controller designed to replace traditional positioners in industrial valve control applications. It delivers exceptional precision, high capacity, and fast response for demanding process control environments.
Product Overview
The FasTrak FT D00ASSA is a high-capacity, high-precision digital-pneumatic valve controller that outperforms conventional positioners. With a high flow coefficient (Cv = 2.0) and advanced digital control, it provides outstanding dynamic performance, accurate positioning, and reliable operation. It supports HART communication for easy configuration and calibration (via HART device or auto-calibration). Compatible with both single-acting and double-acting actuators (spring-return, piston, or diaphragm types), the FT D00ASSA is ideal for applications requiring fast, precise valve control in industrial processes.
