Series M6A

ManifoldsAnderson Greenwood

Five valve manifolds with a 3/16” (4.8mm) orifice for differential pressure natural gas services to 6000 psig (414 barg)

The M6A is for differential pressure transmitters in natural gas applications and is usually supported in the vertical meter tubing from the orifice flange union. Static pressure and calibration test connections are standard.

  • Easy Installation in meter tubing with no additional support generally required.
  • Upstream or downstream ¼” FNPT ports for connecting the static pressure to the meter.
  • Hard or field-replaceable soft seats for bubble-tight performance in abrasive applications.
  • Bonnet-to-body and stem threads isolated from process corrosion - important in sour gas applications.
  • Stem backout prevention eliminates accidental removal while under pressure.
  • FKM O-ring with PTFE back-up ring standard stem packing with long life assured by mirror finish stem in the packing area.
  • Integral hard back seat forms a secondary seal for the stem threads when valve is fully opened.
  • Rolled stem threads increase strength and extend life.
