Things you need to know to properly size a Direct Acting Regulator:
  • Inlet pressure
  • Required Outlet pressure
  • Type of gas to be regulated
  • Load/Capacity? (in Btu or Cfh)
  • What size downstream sensing line does the regulator require?
  • Required connection size
  • Modulating application OR on/off application
  • Do you require an external relief valve?

Ventless Regulators
Norgas Controls has a large variety of ventless regulators for almost any application. These types of regulators are used only for indoors and simplify the installation by not needing to run a vent line to the outdoors.
