<br /> FLOW CHARACTERISTICS NOTE: Placement of check valves too close to sources of unstable flow will shorten the life of '
<br /> the valve and potentially may damage the system.To extend valve life,valves should be installed
<br /> a reasonable distance downstream from pumps,elbows,expanders, reducers or other similar
<br /> devices.Sound piping practices dictate a minimum of five(5)times the pipe diameter for general
<br /> use. Distances between three(3)and five(5)diameters are allowable provided the flow velocity
<br /> is less than eight(8)feet per second(2.4 mps). Distances less than three(3)diameters are not
<br /> recommended and will violate the Victaulic product warranty
<br /> The chart below expresses the flow of water at 65°F/18°C through a full open valve.
