DESCRIPTION

  • Non-slam (spring actuated) check for water or clean fluids
  • Vertical or horizontal installation
  • Replaceable drip tight resilient seat
  • Renewable disc
  • Prevent water hammer in well pumps
  • Silent check valves were developed to eliminate water hammer due to water flow reversal in clear water pump applications
  • Valve opens when upstream pressure exceeds downstream pressure by 1/4 to 1/2 psi
  • An internal spring closes valve just prior to an equalizing pressure on both sides providing a quiet and shock less valve closing
  • Designed for use with Class 125/150 flanges
  • Use flat-faced metal flanges and full-face gaskets only
