Metallized Carbon Corp.

Ball Valve Seats
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.

Metcar 1515 mechanical-grade copper bearings
Metcar 1515 mechanical-grade copper bearings operate without lubrication in dry and dust-prone environments at temperatures up to 750°F. The bearings are non-galling and dimensionally stable, and they have high compressive strength and excellent chemical resistance and conductivity. They can be used in the construction of bearing and thrust washers for use in kilns, kiln cars, oven dryers, dust and fume collectors, ventilating dampers, furnaces and conveyors.
