Smart valve positioner, flameproof explosion-proof Exd, straight stroke, single acting, fail lock, split body anti-high temperature vibration
fully automatic, high accuracy smart valve positioner
Compact, rugged and lightweight, is a fully automatic, high
accuracy smart valve positioner. Featuring auto set-up, auto
configuration and auto calibration, the unit has an integral
auto-manual bypass switch. It offers split range setting,
configurable low flow cut-off and configurable valve output
characterization for unique applications.
The system provides accuracy and vibration-resistance for high
control valve performance, allowing tight process control and
reduction in product variability. It has a non-interactive zero and
span adjustment.
