Model 30 dual-seal ball valves are thoroughly described and illustrated in this free 20-page brochure.
The 2 through 30-in. designs are for pipeline, petrochemical, and process applications. They are declared to “outperform a through conduit gate valve at the price of a ball valve.”
Each body connection has two seals to ensure integrity along with availability in RF, RTJ, and weld end connections. A labeled cutaway depicts ball available with overlays for corrosive applications, primary and secondary upstream seals, blowoutproof stem, ISO mounting flange, and emergency seat injection. The three-piece valves are given full dimensional, tabular specification with schematics. Vertical integration data are supplied.
ASME/ANSI, API, MSS, ASTM standards and specs are cited including API 6D, 600, 603, and 6FA. Operating pressures (ASME B 16.34) are also charted. A full-page trim chart is also provided along with fire-test certification.
