Control Valves
Use of Positioners Minimize the effects of friction & hysteresis / reduce dead band. Increase differential pressure capability. Permit split range operation / high rangeability in slow response loops. Convert a linear flow characteristic to equal percentage (smart). Can have integral I/P transducers.
Direct or Reverse-Acting? DIRECT-ACTING: shaft goes down when command signal increases. Valve closes and flow decreases REVERSE-ACTING: shaft goes up when command signal increases. Valve opens and flow increases
