How to select an industrial gas regulator for a gas train?

Selecting an industrial gas regulator for a gas train is not just about picking a size—

it’s about matching pressure stability, flow capacity, and safety requirements to your burner system.

Here’s a practical, engineering-focused guide.

1. Define the application in the gas train
Start by identifying where the regulator sits:
• Service regulator → reduces supply pressure from utility line
• Line regulator → stabilizes pressure before burner train
• Appliance (burner) regulator → final precise control
Each has different accuracy and capacity needs.

For gas trains (burners, boilers):
You typically need line + appliance regulation, often high stability.

2. Key selection parameters (core checklist)
(1) Gas type
• Natural gas, LPG, hydrogen, biogas, etc.
• Impacts:
• Material compatibility
• Sizing (specific gravity)
Always specify gas composition.

(2) Inlet pressure (P1)
• Max / min supply pressure
• Example:
• 2–6 bar (low pressure line)
• 200 bar (cylinder system)
Regulator must handle full pressure range safely.

7. Typical selection workflow (practical)

1. Define gas type + composition
2. Determine:
   • P1 (min/max)
   • P2 (setpoint)
   • Flow (max/normal)
3. Choose regulator type:
   • Pilot vs direct
   • Single vs dual stage
4. Check:
   • Flow curve
   • Droop & accuracy
5. Verify:
   • Material compatibility
   • Safety devices
6. Confirm standards:
   • EN 88 / EN 334 (EU gas systems)
