Valves for High Temperatures And Abrasive Surfaces

A-T Controls has engineered its M Series metal seat ball valves with specially coated matched balls and seats to stand up to high temperatures, pressures and abrasive materials. The M Series also provides:

An oversized stem to prevent deformation at higher pressures and temperatures.
An Inconel seat spring maintains positive contact between the ball and seat during operation.
Precision CNC machining to ensure the ball and spring live-loaded seats seal tightly for optimal shutoff and tight sealing, even at low temperatures and pressures.
A standard uni-directional shutoff, whereas a bi-directional shutoff can be available for back flow applications.
Ball and seat materials that consist of stainless steel, stellite welded and hard chrome-plated steel, allowing the valves to perform well in applications involving abrasive fluids and steam.
A temperature range from -20 to 661 F and a pressure rating up to ANSI class 600.
A nominal pipe size range from 0.5 to 8.0 inches.
An anti-static device, a blowout-proof stem and a fire-safe design that conforms to API 607 4th edition.
The flexibility to select body materials from WCB, CF8 or CF8M, while special materials are available based upon application.
Availability of 4 connections flanged, threaded, socket weld or butt weld.
2 optional coatings a tungsten carbide coating for heavy slurry environments and a chrome carbide coating for higher temperature applications.
Suitability for the oil/gas, chemical, power generation, pulp and paper, food processing and mining industries.
