  • Threads rolled in a separate cold pressing process to enhance strength
  • Rolled threads ensure smooth thread edges and low operating torques
  • Twice the yield strength required by AWWA eliminates bent and broken stems
  • Bronze stems are available
  • Stainless steel bolts - standard
  • Packing gland bolts and bonnet bolts are stainless steel for corrosion resistance
  • Bonnet bolts are countersunk and capped with hot melt to totally isolate the bolts from corrosive environments
  • O-ring bonnet gasket wraps each bolt to prevent corrosion
