The specs for the CSV1x models all say they handle 1-25 gpm. What does that imply if one is put on a system that puts out more than 25gpm? My system is used for house and lawn irrigation, and the irrigation zones are all sized at 28gpm at 50psi. If this will cause a problem, what can be done short of restructuring the zones to less than 25gpm? I see the CSV2W can go handle up to 50gpm, but the 5gpm minimum seems too high for reasonable residential use.

Can someone explain what the charts in the specs mean (the "System Flow Rate vs. Reduced Pressure Falloff)? What do I need to understand about them?

Thanks,
Ira
