Flowserve uses Hardide Coatings’ tungsten carbide-based coating on its McCanna standard metal seated valve applications.

Tungsten coatings allows Flowserve to offer the base metal in 316SS steel for use in severe service applications requiring metal to metal seating, including abrasive and slurry applications.

Flowserve will offer the Hardide coating as a standard metal seated option for the McCANNA seal top entry ball valve on ½ in to 4 in RP/FP, ANSI 150-1500 and cryogenic to 800OF maximum temperature applications. 
“Hardide coated balls and seats were still operational after more than 70,000 cycles in slurry where Stellite failed in 29,000 cycles,” said Dan Wilson, Hardide’s US-based business development manager.
