larger imageXomox's, patented, live-loaded S2 sealing system provides superior stem sealing in the most demanding applications. The spherical design of the S2 seal and stem assures continuous contact, even during stem side loading. Dual body gaskets are standard, a PTFE chemically inert seal and a secondary FT graphite seal. Xomox's patent No. 6, 837, 482 diamond shaped, thermally assisted PTFE body seal, will seal at all tem peratures in its design range, even during thermal cycling. This unique design takes advantage of the differ ences in the rates of thermal expan sion between the PTFE and metal to enhance the seal. Sizes 12" through 8"ANSI Class pressure ratings of 150, 300, and 600Xomox Ball Valves provide tight shutoff from vacuum through rated pressure at temperatures from -20F to 450F.

Since 1979 the Cam-Tite Ball Valve has become a performance leader in tough-to-handle services. The combination of the patented sealing arrangement and the superior stem seal design has ushered the Cam-Tite into services where its design superiority has proven itself over plug valves and conventional floating ball type valves. Among the services where Cam-Tite Ball Valves have emerged as the solution are the following:Dry ChlorinePhosgeneAnhydrous HFAnhydrous AmmoniaAnhydrous HCLHigh VacuumSteamPCL3VOC5All standard PTFE seats and seals are manufactured using unfilled, unpigmented PTFE. Virgin PTFE provides excellent resistance to the most aggressive chemicals and can handle media at both elevated and semi cryogenic temperatures. Having no filler material, PTFE components are commonly specified for applications where attack of an added filler could occur. Typical applications would be fluorine based chemicals which would attack glass or highly oxidizing media which would deteriorate graphite. Virgin PTFE is commonly used in Cam-Tite Ball Valves specified for hydrofluoric acid and fluorine gas service. Cam-Tite Ball Valves utilizing virgin PTFE seats and seals have a temperature range of -50F to 450F (-45C to 232C).
