Item Details

  • Victor® SR 311 Series High Capacity Carbon Dioxide Flow meter offers 25 - 100 delivery range. Preset at 80 psig. Regulator with maximum inlet pressure of 1500 psig features machined aluminum body, housing cap, 2" brass gauges and 1 3/4" fabric reinforced neoprene diaphragm. Regulator with 320 CGA-inlet connection and CGA-032 5/8" - 18 UNF outlet connections has external self-reseating relief valve and stem type seat mechanism.

  • Machined aluminum body and housing cap
  • 1.75" (44.5 mm) diaphragm fabric reinforced neoprene
  • Stem type seat mechanism
  • High flow CO2 applications (SR 310 100 PSIG) (SR 311/312 100 SCFH) with adequate supply or source
  • Self reseating relief valve (not designed to protect downstream equipment)
  • Sintered inlet filter


  • Core Wire


  • A regulator equipped with a flow gauge is not accurate when a back pressure in excess of 2 psig exists at the outlet
  • Back pressure is caused by a restriction in the apparatus downstream of the flow gauge
  • Metering valves, kinked hoses or even very long hoses are restrictions that can cause back pressure
  • In applications where back pressure in excess of 2 psig can be expected, a regulator equipped with a flowmeter should be used
