Flo-Tite's Van Guard Stem Sealing System, designed to minimize fugitive emissions. Increases safety and provide an immediate ball valve solution to the EPA performance requirements, for valves meeting with a leak rate of 500ppm.
Flo-Tite's Van Guard Seal, state of the art stem sealing system. Incorporating a triple set of valve stem seals. This unique system eliminates the possibility of valve stem leaks in most all media applications.
STAGE I - Front Line
Stage I provides a front line defense against leakage. The blow-out proof stem shoulder has a 45 degree bell shaped slope. The bell shaped design offers more sealing surface, effectively blocking all leak paths during rotation. The wedging action of the portion of the stem is far superior to the common small flat stem shoulder design.
STAGE II - Guide-Seal
The O-ring originated early in valve design and has been a proven performer in high cycle applications. Its basic function reduces the potential of machining imperfections and provides a low torque flexible seal. This center guide also helps to maintain a perfect stem alignment, by eliminating side loading stress which can cause stem leaks.
STAGE III - Live-Seal
Live-seal is considered the intellectual component and the workhorse of Flo-Tite's Van Guard stem sealing system. Working in unison with stages I and II, stage III calls upon the use of V-Ring packing sets which expand sideways as they are compressed and pressurized blocking all air pockets. The Van-Guard stem system is energized by disk or coil springs which continuously adjusts packing compression to compensate for wear, pressure or temperature changes. Whether your service involves volatile org-anic compounds, volatile hazardous chemicals, or air pollutants, Flo-Tite's ball valves are by design dependable, long lasting and fully maintainable. Flo-Tite has various valve solutions and designs that provide end-users freedom of choice for the toughest requirements imposed by the industry and by international standards.
