NEW: pneumatic valve positioner by STI S.r.l.

Smart positioner with high-capacity, high-precision digital-pneumatic valve controller

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.

Key features​

High Flow Precision Control

The unique design allows high speed performance in large volume actuators without additional amplification (e.g. booster or quick exhaust)

Control Algorithms & Hardware

Self calibration on double acting piston, diaphragm, rotary actuator with or without spring; patented adjustable independent ​​control parameter to open and close stroke

Strong Shaft Design

Not sensitive to radial and axial external load caused by mounting and linkages
