Control valve positioner
The SP200 line of smart electropneumatic control valve positioners offers long-term reliability, simplicity and accuracy. The positioner is loop-powered from a 4-20 mA input signal to provide accurate, adaptive position control using pneumatic linear actuated valves. The Hall-effect noncontact position feedback sensor ensures precise valve position control that’s insensitive to vibration. Features include a large LCD, menu-driven software for local calibration or parameter setting and continuous display of percentage of travel.
