Description
Cast Iron Grooved Ball Valve 3700V
Model 3700V features an NSF/ANSI 61 and NSF/ANSI 372 certified cast iron body and the same PFA* fused ball as the 4000 series. It inhibits buildup that accumulates on unprotected ball surfaces and prevents premature valve failure.
Model 3700V is ideally suited for backflow prevention devices and potable water applications. All model 3700V valves are rated 200W at 200°F, and are available in full port from sizes 2” through 6”. With no disc or obstruction in the line, model 3700v easily out-performs any butterfly valve.
Body: Cast Iron/A126 Class B
Connection: Grooved
Ratings: 200 PSI W, 200°F
Stem: Blow-out Proof Stem PFA*- Fused Solid Ball: The 4000 and 3700 Series feature a PFA* fused ball that is more durable, less susceptible to accumulating build-up and longer lasting than an ordinary unprotected ball. With the help of Dupont, we developed a process to impregnate PFA* .008” into a solid metal ball. An additional .004” is added electrostatically for smoothness. Since the PFA* becomes part of the metal, it can’t flake, chip, or peel off. The corrosion and chemical resistance of PFA* has been recognized around the world. With the introduction of this valve we present an affordable (same price as most gate valves) ball valve that will outlast any unprotected metal valve in any use. The lubricity of our PFA* ball allows for lower torque ratings in any application, making it easier to turn. *PFA is an ingredient commonly branded as Teflon®.
Double tapped & plugged bosses allow for venting or draining downstream, or test port for backflow preventer
