Product Details

Product Details

  • 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. This prevents excessive wear of the seat in this area, and provides a consistent wear pattern and long sealing capability
  • 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
  • Opens at 0.5 psi differential
  • Cast iron
  • Wafer
  • Class 125
  • Requires Certification
