A-T Controls M-Series Metal Seat Ball Valves for High Temperatures and Abrasive Surfaces

a-t controls m-series metal seat ball valvesNew M-series metal seat ball valves from A-T Controls 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°F to 661°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.www.a-tcontrols.com
