Mark 57 Series – Externally Piloted Regulator

The Mark 57 provides accuracy approaching that of controller-operated valves and should be considered on most critical applications before other more expensive and sophisticated instrumentation.

The Mark 57, a sliding gate regulator, has a much shorter stroke than the standard globe or plug style valve. The shorter stroke combined with the action of the pilot valve creates a faster and more accurate response.

  • High turn-down ratios – Up to 50:1
  • Versatile Application – Use on steam, air, gas, liquids, or chemicals
  • Sliding gate seats provide straight-through flow for reduced turbulence, quiet operation, fast response, and tight shutoff
