Description
Kartar dual Plate Check Valve Turbo (D.I. Body, PN 16, Wafer Type), available 50 mm to 200 mm at PN 16. Check valves stop reverse flow without any external operation — line pressure alone opens and closes them. On a pump discharge they prevent backspin and the water hammer that follows an abrupt stop. Ductile iron carries considerably more strength and impact resistance than grey cast iron for the same section — the reason it is specified for buried and higher-pressure mains. A wafer body adds almost nothing to the length of the pipe run. The table above gives the price for each size in the range.
