  • Downstream stop shaft stabilizes the discs at high flow rates and prevents them from striking each other, which can cause premature wear, stress on the shaft, and chattering
  • Standards/Approvals: ANSI Specified, API 598, FM Approved
  • Applications: For liquids and gases where flow reversal can cause surge and water hammer
