Norgas Regulator Sizing Tool

To ensure your NGR08 Gas Pressure Regulator meets your system’s requirements, use the Norgas Regulator Sizing Tool.

1. Gas Type – natural gas, LPG, or other non-corrosive dry gases
2. Inlet Pressure – the upstream pressure entering your regulator
3. Desired Outlet Pressure – the pressure you need downstream
4. Flow / System Capacity – the required gas flow rate for your application
5. Pipe Connection Size – to match your system piping
