Coated matched balls and seats are designed to stand up to high temperatures, pressures and abrasive materials. Valves in the M-Series have a temperature range of -20 to 661°F (-28 to 349°C) and a pressure rating up to ANSI class 600. Ball and seat materials include stainless steel, Stellite welded and hard chrome-plated steel, allowing the valves to perform well in applications involving abrasive fluids and steam. Optional coatings include a tungsten carbide coating for heavy slurry environments and a chrome carbide coating for higher temperature applications. An oversized stem prevents deformation at higher pressures and temperatures.
