  • Features
  • Compact design with short face to face dimensions for minimum space requirements
  • Dual shaft design allows interchangeability of shafts
  • Torsion springs close the valve prior to flow reversal
  • Torsion springs exert a lifting motion on the discs, enabling the center "heel" to open first
  • 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 Tested, FM Approved, UL Listed
  • Applications: For liquids and gases where flow reversal can cause surge and water hammer
