Flowserve introduces the Logix 3200IQ and 500SI series of high-performance digital positioners with quick setup and calibration of either diaphragm or piston-operated valves without the need for additional handheld devices. The positioners can be used in compact, lightweight and modular designs. They feature a jog calibrate function that allows the user to calibrate without physical stroke stops, a built-in auto-tuning function and two stage control that can be combined with Flowserve SoftTools software or handheld communicators.
