Model M5A

Gauge ValvesAnderson Greenwood

A ⅜ inch (9.5 mm) orifice multi-port gauge valve that is available with replaceable roddable metal or soft seats for pressures up to 6000 psig (414 barg)

The M5A is designed to be used with gauge mounting and other instrument tie-ins in the process industries without requiring additional penetrations of the main piping.

  • Cost savings through minimized components and process penetrations for instrument installation with reduced possible leak points.
  • Compact design minimizes space requirements; low weight improves connection strength and reduces gauge whip.
  • Unique metal seat has straight through flow path design for reduced plugging in high‑temperature service.
  • Long body option allows up to 4” (102 mm) pipe insulation.
  • Replaceable soft seat; valve operates in dirty service with repetitive bubble-tight shutoff.
  • Mirror stem finish in the packing area enables 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.
  • Easily adjustable packing decreases replacement downtime and increases valve life.
  • Safety back seating prevents stem blowout or accidental removal.
  • ENC plated 316 SS prevents galling or freezing of stem threads.
  • Rolled stem, bonnet and male NPT threads provide additional strength.
