Features

  • Ball end stem eliminates seat galling, provides bubble-tight shutoff and long life. Hardened, non-rotating ball ensures perfectly aligned closure.
  • Packing below threads prevents lubricant washout, thread corrosion, process contamination and eliminates galling.
  • Easily adjustable PTFE packing decreases replacement downtime and increases valve life.
  • Dust cover protects stem from lubricant contamination.
  • Safety back seating prevents stem blowout or accidental removal and provides a metal-to-metal secondary stem seal while in the fully open position.
  • ENC plated 316 SS stem prevents galling or freezing of stem threads. CS valves use a 303 SS stem for 'hard-to-soft' contact to prevent galling.
  • Rolled stem and bonnet threads provide additional strength.
  • Mirror stem finish in the packing area provides smooth operation and extends packing life.
  • Metal-to-metal body-to-bonnet seal in constant compression prevents bonnet thread corrosion, eliminates possible tensile breakage and gives a reliable seal point.
  • Metal seat can be resurfaced for longer valve life.
