The new M-series metal seat ball valves from A-T Controls stand up to abrasive fluids, high pressure, steam and high temperatures with an oversized stem and larger ball design to prevent leaks. They are engineered with specially coated matched balls and seats for the oil and gas, chemical, power generation, pulp and paper, food processing and mining industries. The M-Series valves have a temperature range of -20F to 661F, and a pressure rating up to ANSI class 600. They are 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 include a tungsten carbide (TC) coating for heavy slurry environments, and a chrome carbide (CC) coating for higher temperature applications. A larger ball design provides a tight seal, preventing leakage, and an Inconel seat spring maintains positive contact between the ball and seat during operation while an oversized stem prevents deformation at higher pressures and temperatures. There are four connection options on the M-Series valves: flanged, threaded, socket weld and butt weld. Body material options include WCB, CF8 and CF8M.
