Smart valve positioner, flameproof explosion-proof Exd, straight stroke, single acting, failsafe
Auto setup: The auto-setup function is a fully-automatic configuration program which specifies the actuator and adjusts the zero and span of the valve. The program can be turned on simply from an external switch so that adjustments to the valve can be performed quickly and safely in hazardous areas.
Self-diagnostic: The self-diagnostic function provides with the ability to check the status of the positioner at any time and to alert in case of failure.
Input range: Configurable to any required range for split range
Flow characteristic: Linear, EQ%, Quick opening or custom user characteristics
Actuator type: Single or double acting actuator (optional reversing relay required)
