Carbon-Graphite Ball Valve Seats
Metallized Carbon Corporation (Ossining, NY) has announced the availability of carbon-graphite ball valve seats for use in valves designed to handle hot liquids or hot gases. The carbon-graphite ball seats are ideal for use in temperatures from approximately 350 degrees F, where plastic ball valve seats begin to soften. They can be used in temperatures up to 800 degrees F in oxidizing environments, where high temperature carbon-graphite materials start to oxidize. They are also excellent for fire safe petroleum industry ball valves, which must operate freely after a simulated fire test in which the valve is heated to 1400-1800 degrees F.
