High-temp/pressure/abrasive surface ball valves

摘要

New M-series metal seat ball valves incorporate specially coated matched balls and seats to withstand -20° to +661°R, ANSI class 600 pressures, and abrasive materials in oil/gas and chemical operations. Valve ball and seat materials include stainless steel, stellite welded, and hard chrome-plated steel to function in abrasive fluids and steam. Optional tungsten carbide and chrome carbide coatings are also offered for heavy slurry environments and higher temperature applications.
