Only Xomox Process Ball Valves embody all the quality, performance, value, and safety features required in process applications. The basics: Xomox Process Ball Valves are available in the following configurations: One-piece flanged. Two-piece flanged. Three-piece screwed, socket-weld, and butt-weld ends. Sizes 1/2 through 8 inches. ANSI Class pressure ratings of 150, 300, and 600.

Thermally assisted sealing. Xomox's diamond shaped, thermally assisted PTFE body seal, will seal at all temperatures in its design range, even during thermal cycling. To enhance the seal, this unique design takes advantage of the differences in the rates of thermal expansion between the PTFE.
