Third-party Proof ofDesign Testing was successfullycompleted and flow testing wasperformed at the Utah StateHydraulics Lab, one of the premiertesting labs in the thousands of field installa-tions throughout the world, theAmerican-BFV design has provendependable since valves are certified for use indrinking water in accordance withNSF/ANSI 61 and are WQAC ertified American-BFV provides thefeatures that engineers and usershave requested and are includedin the AWWA C504 and C516 Butterfly Valve standards.
5 TheAmerican-BFV is designed to pro-vide long life and trouble-freeperformance. If maintenancebecomes necessary, the Valve isalso designed for easy field ser-vice. The shaft seal incorporatesV-type packing which is easilyreplaced in the field withoutremoval from the line. Adjust-ment of the resilient seat is easilyperformed with a torque wrench,as compared to epoxy filled seatsthat require special equipmentand materials or bonded seatsthat cannot be replaced or adjust-ed in the field. The unique Tri-Loc seat reten-tion system assures seat integrity by securing the seat throughthree different mechanical meth-ods to assure long-term depen-dable service, See Figure 1. Allseat designs provide excellentseating but only the Tri-Loc pro-vides ease of adjustment orreplacement in the field if American-BFV disc is ductileiron in all sizes.
6 The addedstrength allows the disc design tohave a smaller cross section pro-viding improved headloss charac-teristics. The American-BFV willwithstand flow rates and pressuretransients beyond the maximumAWWA pressure the latest in valvetechnology assures a high-qualityvalve that will provide long ser-vice. The design process utilizedSolid Modeling and Finite ElementAnalysis (FEA) of the key structu-ral components. Flow and torquedata was derived from flow tests,mathematical models and Com-putational Fluid Dynamics (CFD).Manufacturing technology usesautomated process control in thefoundry and ISO 9001 controlledmanufacturing processes. Everyvalve is tested in accordance withAWWA C504 and Tri-Loc seat retention system provides reliable sealingand positive mechanical retention of the Valve seat whileallowing easy adjustment or replacement in the seat is secured by three methods: 1) clamp force, 2)through the seat bolting and 3) opposing machined registersin the disc and seat retaining ring.
7 Clamp force is provided bytightening the Nylok* cap screws. Tightening the screwsapplies pressure to the serrated seat retaining ring which inturn creates a clamp force on the rubber molded same cap screws provide through-bolting seat retentionby passing through precision molded holes in the rubber , molded shoulders in the rubber seat are captured bymachined registers in the disc and retention ring preventingoutward movement of the seat.*Nylok is a registered trademark of Nylok corporation. 3 SEAT RETAINING RINGRUBBER SEATDISCCAP SCREWTHROUGH SEATBOLTINGNYLOKPLUGUS Patent No: 6,244,567 Figure 1.
