New Metal Seat Ball Valves for High Temperatures and Abrasive Surfaces

New M-series 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 the oil/gas, chemical, power generation, pulp and paper, food processing and mining industries. Valves in the M-Series have a temperature range of -20 to 661 degrees F, and a pressure rating up to ANSI class 600. M-series 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. Two optional coatings are also available – a tungsten carbide (TC) coating for heavy slurry environments, and a chrome carbide (CC) coating for higher temperature applications. An oversized stem prevents deformation at higher pressures and temperatures. Larger ball design provides a tight seal, preventing leakage, and an Inconel seat spring maintains positive contact between the ball and seat during operation.
