Ball check valves allow free flow in only one direction, prevent backflow,
and are for applications where poppet style valves may not be suitable (such
as media with contamination, viscous fluids, etc.). They are trouble
free with large flow paths. The need for closely mating surfaces and sliding
parts has been eliminated by the conical tension spring and seal seat design.
