A top-mount valve positioner compatible with any system
Badger Meter
The Research Control SRD991 valve positioner (photo) mounts directly to the top of a control valve with a rugged linear potentiometer, avoiding hysteresis between the positioner and actuator. With integrated network communications, including HART, Profibus-PA and Foundation Fieldbus H1, the SRD991 valve positioner is compatible with any system’s distributed control system (DCS) or process logic controller (PLC), according to the company.
