Ball valve seats can take the heat.
Metallized Carbon's carbon-graphite ball valve seats are for use in valves designed to handle hot liquids or hot gases. The ball valve seats are available in more than 150 grades of the company's proprietary carbon/graphite material. The ball seats are ideal for use in temperatures above 350 F, where plastic ball valve seats begin to soften. They can be used in temperatures up to 800 F where high temperature carbon-graphite materials start to oxidize. They can also perform as fire-safe petroleum industry ball valves, which must operate freely after a simulated fire test in which the valve is heated to 1,400 to 1,800 F.
