BelGAS | Itron

BelGAS high pressure regulators are designed for farm tap and gas field applications. Cast steel and NACE compatible versions with stainless steel trim are available for high pressure aggressive gas applications such as production and gas storage.

Itron (formerly Actaris/Schlumberger Rombach) spring loaded regulators are DIN-DVGW approved and include a variety of safety features including Internal Relief Valve (SBV/IRV), Shutoff valve for Upper and Lower Pressure shutoff (SSV/OPSO) with added thermal shutoff, and a Double Safety Diaphragm design.

Model 133/233 regulators are redesigned versions of the widely used 143/243 lines. They are suitable for use in gas distribution systems as well as on individual appliances such as boilers, furnaces and generators. They can be used with all non-aggressive gasses. Other Rombach models available upon request.

Spacer Plates

  • For replacing 2" Flanged AMCO 1800 series with Itron (Actaris/Schlumberger) B34/B38 Series Regulator.
  • Precision machined 7/16" wide spacer plate with 2" flat faced flange pattern is wafered in between gaskets and installed on the inlet flange of the regulator.
  • The result is that a standard 10" flange to flange regulator (such as an Actaris or Fisher regulator) can be substituted for 10 1/2" F-F AMCO regulator.
