4000 Family GraphicCast iron flanged ball valve with Teflon® fused ball

Model 3700 features an epoxy-coated cast iron body and the same TEFLON® fused ball as the 4000 series. It inhibits buildup that accumulates on unprotected ball surfaces and prevents premature valve failure. The same ANSI B16.10 end-to-end dimensions as flanged gate and plug valves makes this one an easy decision.

Model 3700 is ideally suited for backflow prevention devices and potable water applications. All model 3700 valves are rated 200W at 200°F, and are available in full port from sizes 2" through 8". With no disc or obstruction in the line, model 3700 easily out-performs any butterfly valve.
