Electro-pneumatic valve positioner offers high accuracy

July 31, 2016   Don Horne




ABB haEDP300s unveiled its EDP300 series digital positioner for regulating air-driven linear and rotary actuators, including control valves. The new design incorporates an advanced algorithm for excellent accuracy and speed. It also offers ABB’s HMI with menu-driven programming and control selection of options, saving time and cost. The EDP300’s diagnostics include optional pressure sensors to determine valve and actuator performance, allowing users to monitor actuator conditions in real time while improving process reliability. The unit also incorporates a partial stroke test (PST) function for in-process verification of valve integrity. With an integrated valve signature function, testing and verification of actuator and positioner assembly baseline performance can be completed without the need for additional hardware.
