The FNW321ASWK is a 2-inch, three-piece weld-socket ball valve built from WCB (cast carbon steel) for durable industrial service. This FNW model—identified as FNW321ASWK and listed as Fig. 321A in the catalog—uses a three-piece body design for easier maintenance in line. Weld-socket connections enable direct welding to piping, delivering a permanent, leak-tight shutoff in steel pipelines.
