The 2-1/2 in. ductile iron double door wafer check valve (part 963025) uses twin spring-loaded aluminum bronze doors for fast, non-slam closure and very low headloss. The compact wafer body installs between ASME B16.1 Class 125 / ASME B16.5 Class 150 flanges, in vertical or horizontal runs.

  • Wafer pattern: a fraction of the weight and face-to-face length of a swing check
  • Excellent flow characteristics and low pressure loss at high flow rates
  • Resilient seat seals tight even at low differential pressure
  • Mounts vertical or horizontal
