“FREE FLOATING BALL, METAL SEATED & FORGED DEISGN”

The DFM series metal seat ball valves are engineered with specially coated matched balls and seats to stand up to high temperatures, high pressures, and abrasive materials encountered in the power generation industry. Valves in the DFM series have a temperature range of –20F to 661F and a pressure rating up to ANSI class 2500.

DFM series ball and seat materials include stainless steel, satellite-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 coating for heavy slurry environments and a chrome carbide coating for higher-temperature applications.

Materials include forged carbon steel, low-temperature carbon steel, stainless steel, Monel, Hastelloy, Alloy 20 and others as required. These materials are compliance with NACE standard MR 0175 specifications.
