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 an 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.

Sizing Cheat Sheet

7 Things You Need for Natural Gas Regulator Sizing

To select a natural gas regulator, 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 are the gas load and capacity? What are the minimum and maximum expected capacities in BTU/hr? Or CFH?
   • Flow is typically expressed in CFH (cubic feet per hour or CFM (minute)
   • 1 CF = one cubic foot of gas = 1,000 Btu
   • 1 CFH = one cubic foot of gas per hour = 1,000 Btu/hour
   • 100 CF = 100,000 Btu = 1 Therm
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 about Gas Line Pressure versus Appliance Control regulators.
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.
