Built to a Higher Standard
Precision MachiningPrecision Machining All Tru-Flo valves are supplied with a precision-machined solid stainless steel ball. Balls are polished to a mirror finish to provide lower operating torque, longer life cycle, higher performance and bubble tight shut off. All balls are provided in 316L material for long life cycles and durability. We employ the latest techniques and technology in our ball manufacturing processes.
Intelligent Stem DesignIntelligent Stem Design Tru-Flo valves offer a heavy duty, 316 stainless stem design. All stems are internal entry and simplify lever mounting and flow direction. All stems are of an anti-blowout design to ensure maximum safety. Stem design meets ANSI B16.34 specifications and material meets ASTM A276. Pyramidal stem and seal along with double Viton (R) o-ring seal effectively blocks any leak path from forming during rotation.
CastingsCastings of a Higher Calibre The highest quality investment casting process is used for both stainless steel and carbon steel valves for all designs from sizes ¼” through 4”. Body wall thickness is designed in strict adherence to ANSI B17.34 and all ASTM standards. Each casting is marked with a foundry heat code number which allows for full traceability. All valves are 100% tested and inspected prior to shipment and material specifications can be provided upon request.
