The Flo-Trol® Automatic Flow Control Valves are designed for maintaining constant flow. Flow rates are maintained to within ±15%, between 15 and 125 PSI (1 to 8.6 bar). The flow rate will vary, due to manufacturing tolerances and water temperatures. Valve bodies are constructed of stainless steel with a Buna-N orifice (NSF/ANSI 61 certified).
Other features include sizes 3/8″ thru 1 1/2” (0.25 – 30 GPM*), with a max temperature rating of 180ºF, and they are also NSF/ANSI 61 and 372 Certified. They can be used in booster pump systems and domestic water systems.
