Flowserve Logix 520MD Smart Digital Valve Positioner with HART 5/6/7 Auto-tune Algorithm and IP66/NEMA 4X Enclosure
제품 설명
Product Overview The Flowserve Logix 520MD is a high-performance digital valve positioner that communicates over HART. It receives a two-wire 4-20mA control signal and provides a proportional pneumatic output to drive a valve actuator. The unit is powered entirely by the 4-20mA loop and controls single-acting actuators with linear and rotary mountings. The positioner uses a multi-variable gain tuning algorithm, which allows large step changes with minimal overshoot while
