Metal-to-metal body joint of the Tufline full-port lined valve family controls compression of valves' lining for heat and stress cracking resistance. Cast-in recesses and machined grooves lock lining to valve body and ball making lining blowout virtually impossible. Both full-port and standard-port models fully conform to ANSI B16.10 dimensional specifications for short-pattern flanged-end ball valves. Choices include standard stem packing or live-loaded, multiple-element stem packing. Seats are easily replaced. Xomox Corp. 4444 Cooper Rd. Cincinnati, OH, 45242
