Sizing Natural Gas Regulators

 In Gas Regulators, Measurement and Control of Natural Gas

As a stocking distributor of regulators, my customers often ask which natural gas regulator to use for a particular application. I usually ask a few questions and direct them to a product. Occasionally a client will ask, “What’s the secret to selecting the correct gas pressure regulator?”

There’s no secret, and I am happy to share the information.

Natural Gas Regulator Sizing

Here are six things you need to know to size your natural gas regulator.

  1. What type of gas are you regulating? While most of my customers inquire about natural gas or methane, I can help you control other fuel gases such as propane (LPG).
  2. What is the inlet pressure? If you do not have a pressure gauge, you can always call your gas distributor or inquire about some of the excellent gauges (gages) we have available. The units of measure here are either PSIG or WC.
  3. What is the desired outlet pressure? The units are usually WC, though they may be PSIG.
  4. b42 gas pressure regulatorWhat is the gas flow range? Alternatively, what are the gas load and capacity? What is the minimal and maximum expected capacity in units of CFH, MBH, or BTUH?
  5. What is the pipe size? Regulators are usually available in sizes ½” through 4″.
  6. Is the regulator to be indoors or outdoors? If the regulator is indoors, consider a line pressure regulator with a vent limiter and an overpressure protection device (OPD). More available on this on Gas Line Pressure versus Appliance Control.

It’s also helpful to know if the regulator is going inside or outside, and if noise is a concern, and what the altitude is.

Selecting the Correct Unit

If you have the answers to these questions, you have the information needed to select the correct regulator. Just know that you find yourself studying endless sizing charts and graphs.

  1. Get out your magnifying glass and pore through those manufacturer sizing charts available in the catalogs.
  2. Try the sizing programs offered by various manufacturers, though, they are not foolproof, and until they are, I personally still size my customer’s regulators the old-fashioned way.

    I have a natural gas well on my farm
    Has been for over 80 years.
    They use it to heat hose and run gas lights.
    Then just just a hot water heater.
    They told me it lost it pressure.
    I unhooked it from house from a regulator and found it has 21psi.
    We hooked up to a paint regulator
    Cutting the pressure down as low as we could hook up to a natural gas furnace and it burned very clean, and the durance cycled.
    Question; need to know how or what size of regulator I will need to cut pressure down from 21psi in to about 3psi to run a 120 btu boiler?
