Understand the 4 Gas Regulator Types

Before sizing, understand the regulator’s purpose. There are four primary applications for gas regulators:

  1. Appliance regulators control the gas pressure running to an appliance.
  2. Line gas regulators control the gas pressure between a service regulator and appliance regulator on a gas line.
  3. Service regulators reduce service line gas pressure to the desired delivery pressure.
  4. Pressure regulators reduce, control, and maintain the pressure of a specific portion of a pipe system.

7 Things you Need for Natural Gas Regulator Sizing

Here are the seven things you need to know to size your natural gas regulator:

  1. Gas type – What type of gas are you regulating? While most customers inquire about natural gas or methane, we also help control propane (LPG).
  2. Inlet and outlet pressure – What is the inlet and desired outlet pressure? The units of measure here are either PSIG or WC. If you do not have a pressure gauge, you can always call your gas distributor or inquire about some of our excellent gauges (gages) available.
  3. Gas flow – What is the gas flow range? Alternatively, what are the gas load and capacity? What is the minimal and maximum expected capacity in BTU/Hr, CFH?
  4. Pipe size – What is the pipe size? Regulators are typically available in ½” through 4″.
  5. Altitude – Altitude affects regulator sizing. Atmospheric pressure reduces with altitude, so we must ascertain the regulator’s intended elevation. Learn more about the effects of altitude.
  6. Location – Is the regulator to be indoors or outdoors? Consider a line pressure regulator with a vent limiter and an overpressure protection device (OPD) if indoors. Learn more on Gas Line Pressure versus Appliance Control.
  7. Noise – Is noise an issue? Or vibrations? Humming, buzzing, chugging, and vibrations can occur for various reasons (harmonic instability, hunting, feedback) in a gas system.

Selecting the Correct Unit for an Application

If you have the answers to the seven items mentioned above, you have what you need to select the correct regulator. Here are your options on how to proceed:

  1. Get out your magnifying glass and pore through those manufacturer sizing charts available in the regulator datasheets.
  2. Try the sizing programs offered by various manufacturers, though they are not foolproof. Until they are, I personally still size my customer’s regulators the old-fashioned way.
  3. Call us at 303 697-6701 – or message us – and we will be happy to assist you with sizing your application.

    Hi
    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?

    LPG is also knowns as Liquefied Petroleum Gas or Liquid Petroleum Gas. LPG is simply a mixture of hydrocarbon gases like propane or butane etc are commonly used as fuel in heating appliances, hospitality, calefaction, construction, sailing and fishing sectors, and vehicles. It is used as an aerosol propellant and a refrigerant. Liquefied Petroleum Gas is mainly for cooking in many countries for economic reasons because is is one of the best-preferred fuel sources.
