M-series Metal Seat Ball Valves

M-series Metal Seat Ball Valves

A-T Controls' 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 661F, 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 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 and features include an anti-static device, a blowout-proof stem and fire-safe design that conforms to API 607 4th edition.
