Metal Seat Ball Valves withstand severe conditions.
January 31, 2011 -
M-series employs coated matched balls and seats of stainless steel, stellite welded, and hard chrome-plated steel that withstand abrasive materials, temperatures from -20 to +661°F, and ANSI class 600 pressures. Oversized stem prevents deformation, ball design prevents leakage, and Inconel® seat spring maintains positive contact between ball and seat during operation. Available in 0.5-8.0 in. nominal pipe sizes, valves offer flanged, threaded, socket weld, and butt weld connection options.

New M-Series Metal Seat Ball Valves Ideal for High Temperatures and Abrasive Surfaces
High-performance metal seat ball valves stand up to abrasive fluids, high pressure, steam and high temperatures with an oversized stem and larger ball design to prevent leaks
New 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.
M-Series valves are available with four connection options - flanged, threaded, socket weld and butt weld - and body material options include WCB, CF8 and CF8M. Special material is available based on application. Nominal pipe size (NPS) range is 0.5 to 8.0 inches. A uni-directional shutoff is standard, with a bi-directional shutoff available for back flow applications.
Precision CNC machining ensures the ball and spring live-loaded seats seal tightly for superior shutoff and tight sealing, even at low temperature and pressure. Safety features include an anti-static device, a blowout-proof stem and fire-safe design that conforms to API 607 4th edition.
Details and specifications for the entire line of AT-Controls' metal seat ball valves and accessories are available in two new product brochures, "M Series Floating Metal Seat Ball Valve" and "M Series 3-piece High Performance Metal Seat Ball Valve."
