  • The above curves are based on the flow of clean water at ambient temperature.
  • Preferred piping standards recommend placing check valves 5 to 10 pipe diameters from any turbulence producing device, i.e. pumps, elbows, etc.
  • Maximum recommended flow velocity of 10 ft./sec. 
We recommend that the valves be installed 7 to 10 pipe lengths away from the turbulence.
