Description
Veeson’s ductile Iron Wafer Type Swing Check Valve, S.S. Flap (CF-8) (PN-16) is supplied in 40 mm to 200 mm. 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. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
