A-T Controls' M-series metal seat ball valves are engineered for high temperatures and abrasive surfaces

M-series metal seat ball valves from A-T Controls are engineered to stand up to high temperatures, pressures and abrasive materials. 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. 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 is designed to prevent deformation at higher pressures and temperatures. The larger ball design is engineered to provide a tight seal and prevent leakage, and an Inconel seat spring is designed to maintain 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.
