Key Categories of Gas Regulators

Gaining insight into the regulator's intended function is essential before proceeding with sizing. The principal applications for gas regulators include:

1. Appliance regulators: These manage the gas pressure supplied to an individual appliance.
2. Line gas regulators: They control the gas pressure in the section between a service regulator and an appliance regulator within a gas line.
3. Service regulators: These reduce the gas pressure from the service line to the requisite delivery pressure.
4. Pressure regulators: Their function is to lower, manage, and maintain the pressure within a designated segment of the piping system.

Essential Factors for Sizing Natural Gas Regulators

When sizing a natural gas regulator, keep in mind the following seven crucial factors:

1. Type of gas: Identify the gas you are regulating, whether it be natural gas, methane, or propane (LPG).
2. Inlet and outlet pressures: What are the specific inlet and desired outlet pressures? Measurement units may include PSIG or WC; if you lack a gauge, don't hesitate to reach out to your gas distributor or check our gauges.
3. Gas flow: Determine the gas load and capacity, as well as the minimum and maximum expected capacities in BTU/hr or CFH.
   • Flow is normally expressed in CFH (cubic feet per hour) or CFM (cubic feet per 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 diameter: Know the size of the pipe; regulators are typically available in sizes from ½” to 4”.
5. Altitude considerations: Be aware that altitude impacts regulator sizing due to reduced atmospheric pressure, necessitating knowledge of the intended elevation.
6. Installation location: Will the regulator be situated indoors or outdoors? Consider a line pressure regulator with a vent limiter and overpressure protection device (OPD) for indoor settings.
7. Noise factors: Evaluate whether noise or vibrations are a concern—issues like humming or buzzing can stem from harmonic instability or feedback within a gas system.
