New electro-pneumatic valve positioner offers high accuracy and speed for linear and part-turn actuators

摘要

ABB's new EDP300 series digital positioner is designed for regulating air-driven linear and rotary actuators, including control valves. The new design incorporates an advanced algorithm to position the valve actuator with what it characterizes as unsurpassed accuracy and speed. It also offers ABB's HMI with menu-driven programming and control selection of options, saving time and cost. EDP300's diagnostics include optional pressure sensors to determine valve and actuator performance, allowing engineers to monitor actuator conditions in real-time and improving process reliability.
