Proportional Valves

Proportional control of pneumatic pressure

Proportional Valves

Proportional valves convert an electrical signal into a proportional pneumatic output. The proportional valves engineered by Valves, offer superior performance over conventional valves. The MAC Proportional Pressure Controller (PPC), unlike I/P or V/P transducers, employs two valves to control output pressure. The PPC controls output pressure by continuously measuring downstream pressure and comparing it to the command signal. The PPC quickly responds to the detected need for higher pressure by actuating the fill valve. Correspondingly, if the need for lower pressure is detected the PPC actuates the dump valve. The result is highly consistent, repeatable, and efficient performance.

The MAC design approach to pressure control has several important advantages:

  • Smaller, more lightweight units
  • Excellent flow vs. cost compared to competitive units
  • High flow, fast, and repeatable response times
  • Eliminates ‘undershoot’ and ‘overshoot’ problems associated with unbalanced valve design units
  • Incorporates existing MAC valves long life technology to insure many trouble free cycles

Options Include:

  • Covered or Non-Covered Models
  • Different material options for washdown/corrosive environments
  • Various command and feedback options
  • Wide array of operating pressures and resolutions/accuracies
  • Varrying flow rates available for perfect fit to application
