Model M5/M51

Gauge ValvesAnderson Greenwood

Compact, lightweight multi-port valves for pressures up to 6,000 psig (414 barg) or 10,000 psig (690 barg)

M5 valves allow the versatile positioning of gauges or pressure switches without requiring additional penetration of the main piping. The M51 is a metal seat version for high-pressure applications.

  • Cost savings through minimized components and process penetrations for multiple instrument installations with reduced possible leak points.
  • Compact design minimizes space requirements; low weight improves connection strength and reduces gauge whip.
  • Long body option allows up to 4” (102 mm) pipe insulation.
  • Replaceable soft seat and can operate in dirty service with repetitive bubble-tight shutoff.
  • Repairable metal seat can be resurfaced without removing the valve from the line.
  • Ball end stem eliminates seat galling, provides bubble-tight shutoff and long life. Hardened, non-rotating ball ensures perfect alignment closure.
  • Packing below threads prevents lubricant washout, thread corrosion, process contamination and eliminates galling.
  • Easily adjustable packing decreases replacement downtime and increases valve life.
  • 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 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.
  • Metal-to-metal body-to-bonnet seal in constant compression prevents bonnet thread corrosion, eliminates possible tensile breakage and gives a reliable seal point.
