Series MST metal-seated trunnion ball valves are presented in this free datasheet for severe service topside
and subsea applications.
The 2 through 8 in. designs are rated ANSI 1500 and 2500; API Class 5000 and 10000. They are shown and described to comprise tungsten carbide overlay on ball/seat mating surfaces, lapped to each other for outstanding seal. Other features emphasized include capture elastomer face seals on all external connections as well as blowoutproof stem and retainers. Double-block-and-bleed design is featured for testing seat integrity.
Models are subjected to Score’s “Flow Testing in Abrasive Duty” test which is explained in the datasheet.
