These carbon-graphite seats are available for use in ball valves designed to handle hot liquids or hot gases. The seats come in more than 150 grades of the company’s oil-free, self-lubricating carbon/graphite materials. With a high degree of chemical compatibility, they are designed for use in the most severe chemical environments, including applications with temperatures to 350°F (where plastic ball valves begin to soften); in oxidizing environments, they can be used at temperatures up to 800°F. They are also appropriate for fire-safe petroleum industry ball valves, which must operate freely after a simulated fire test at 1,400–1,800°F.
