Valve positioner
Badger Meter’s Research Control® SRD991 top-mount valve positioner mounts directly to the top of a control valve with a rugged linear potentiometer. The positioner uses a linear connection, which mitigates hysteresis between the positioner and actuator by feeding back the actual position of a valve actuator, providing significantly improved flow control. The SRD991 top-mount positioner is available with an LCD screen, protocols (HART, PROFIBUS-PA and FOUNDATION Fieldbus H1) and two levels of diagnostics.
