O-Ring encapsulated in the back of the seat, a unique flex-load energized seat design Tech Bulletin Page valve stems feature a NAMUR stem slot for ease of limit switch mounting Parallel flat stem head for positive ball position indication 2 pc design of diamond shaped packing gland preventing side loading due to uneven adjustment V-Ring Packing Rings Form a Rigid, High Cycle Seal O-Ring serves as second barrier for stem leakage Grounding antistatic devices at two locations enable electricity continuity Tapered Thrust Bearing Provides an Excellent Long Life Bearing Support Up to 6, Precision Investment Casting, Shell/ Wall ANSI B6.3 Fully Encapsulated Graphite Gaskets Isolates media from atomsphere Bolts and Nuts of High Quality and High Strength Ensure Structural Strength and Sealing Intergrity Flo-Tite s Flanged series valves with graphite stem packing meet the highest fire safety standards under extreme conditions. In the event of a fire, after heat destroys the primary resilient seat, the ball makes contact with the secondary metal seat, forming a secure seal. The body seal, composed of stainless steel and graphite wound into a spiral, prevents external leakage. The graphite stem rings prevent stem leakage.

Size: 2/2 ~ Ball Design Added Safety Feature Pressure Relieving & Equalizing Seat Design Specially designed seats allow equaliza tion of pressure in the ball cavity which reduces operating torque and increases seat life. All balls are provided with a / hole drilled into the stem slot of each ball to prevent excessive pressure build up in the cavity from trapped liq uid when the valve is in the open position.

7 High-Tech Design Features Flo-Tite s Van Guard Sealing System, designed to minimize fugitive emissions. Increases safety and provide an immediate ball valve solution to the newer 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 5 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 inperfections 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 expands sideways as it is compressed and pressurized blocking all air pockets. The Van-Guard stem system is energized by disk or coil springs which continueouly adjusts packing compression to componsate for wear, pressure or temperature changes. Whether your service involves volatile organic 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 provides end-users freedom of choice for the toughest requirements imposed by the industry and by international standards. Flex-Load Energized Seat Design Size /2-2 Anti- Extrusion Packing O-Ring Size 2/2-2 Coil Spring Anti- Extrusion Packing O-Ring Tech Bulletin Page 6- Tab Washer Belleville Washer Follower Conical Front Seal Packing Gland Energized Follower Conical Front Seal Seat O Ring Seat Ball Upstream Pressure O Rings are inserted behind valve seats. The O Ring exerts only a minimum amount of pressure on the seats that in turn helps seal on both upstream and downstream sides of the ball. Also, helps provide additional seat memory. Ideal for high cycle, very low pressure & vacuum service applications. Flanged Valves with Media Containment Units The I-SO-Mount platform is ideal for the addition of our secondary containment units. Flo-Tite s media containment unit offers in-line maintenance for stem repair, protection for high temperature service, fugitive emission monitoring for early leak detection, positive displacement. It also can be used as a high-tech stem extension. See Tech Bulletin Page 0. Fugitive Emission Top Bonnet Design
