Model M9

Gauge ValvesAnderson Greenwood

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

M9 block and bleed valves are suitable for isolation and venting of static pressure gauge and instrument installations.

  • 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.
