Smart valve positioner, dust explosion-proof ExtD, angular stroke, single acting, fail lock, split body anti-high temperature vibration
intelligent valve positioners are electro-pneumatic valve positioners that are equipped with microprocessors and operate control valves precisely with PID algorithm, with flameproof type explosion-protected construction.
Unlike conventional electro-pneumatic positioners, positioners have various functions such as auto calibration, forceful shutoff and flow characteristic change, and can show extremely improved performances of operability and functionality.
HART Protocol communication is equipped as a normal function and analogue travel transmitter is optional.
These functions are very useful for plant maintenance by remotely monitoring the operating condition of control valves.
