A valve with an interchangeable hard or soft seat and an integral bleed plug specifically designed to facilitate safe, compact, economical gauge installation and operation


  • Packing below threads prevents lubricant washout, thread corrosion, process contamination and eliminates galling.
  • Easily adjustable packing decreases replacement downtime and increases valve life.
  • Metal-to-metal seated bleed plug enables safe pressure venting without breaking threaded connections.
  • Safety back seating prevents stem blowout or removal during operation and provides a metal-to-metal secondary stem seal while in the fully open position.
  • ENC plated 316 SS prevents galling or freezing of stem threads.
  • Rolled stem, bonnet and male NPT threads provide additional strength.
  • Mirror stem finish in the packing area enables smooth operation and extends packing life.
  • One-piece handle design prevents loss due to vibration or during maintenance.
  • Soft or metal seat for bubble-tight shutoff is field-replaceable for easy maintenance.
  • Extended valve life: damaged soft seat can be removed, leaving a metal seated valve.
