Flowserve Logix 520MD Smart Digital Positioner with ASCO Solenoid Valve HART Pneumatic Control
منتوج وصف
Product Overview The Flowserve Logix™ 520MD+ is a two-wire, 4-20 mA digital valve positioner that uses the HART protocol for bidirectional communication. It is a fully electronic and pneumatic closed-loop instrument designed for precise stem-position control of single- or double-acting linear and rotary actuators. The positioner is powered solely by the 4-20 mA loop (minimum start-up current 3.8 mA) and incorporates an inner-loop (pilot-relay) and outer-loop (stem-position)
We sourced Masoneilan SVI3 valve positioners for a refinery project in UAE. The delivery was fast and the technical support was very professional. Everything worked perfectly during commissioning
