Metal seat ball valves are engineered with specially coated matched balls and seats to stand up to high temperatures, pressures, and abrasive materials encountered in oil/gas, chemical,

power generation, pulp and paper, food processing, and mining industries. Metal seat ball valves have temperature range of -20 to 661°F, and pressure rating up to ANSI class 2500. Ball and seat materials include stainless steel, stellite welded, and hard chrome-plated steel, allowing valves to perform well in applications involving abrasive fluids and steam. Two optional coatings are also available –tungsten carbide (TC) coating for heavy slurry environments, and chrome carbide (CC) coating for higher temperature applications. Oversized stem prevents deformation at higher pressures and temperatures. Larger ball design provides a tight seal, preventing leakage, and Inconel seat spring maintains positive contact between ball and seat during operation.
