Steady Pressure. Reliable Combustion.
Gas Pressure Regulators \ Industrial Combustion and Gas Train Applications
Combustion Plus stocks Karl Dungs FRI series and Sensus 243 and 496 gas pressure regulators for combustion systems across industrial heating, process equipment, and commercial gas applications. Unregulated or unstable gas pressure causes burner lockouts, process interruptions, and safety shutdowns. Having the right regulator on the shelf prevents all three.
- Dungs FRI series available in 1/2 in. to 2 in. NPT with CE and CSA approvals
- Sensus 243 serves boilers, burners, ovens, and process heating equipment
- In-stock regulators typically ship next business day
How Do Gas Pressure Regulators Keep Combustion Systems Running Safely?
Industrial combustion systems require consistent outlet pressure regardless of fluctuating inlet conditions. Without reliable regulation, burner performance degrades and flame safeguard systems trip. Karl Dungs FRI series regulators maintain output pressure from 1 in. W.C. to 60 in. W.C. with an integrated 50-micron gas filter and direct-mount compatibility with Dungs A2 pressure switches.
- FRI spring-loaded design holds setpoint across inlet swings up to 200 in. W.C.
- Integrated 50-micron filter removes upstream contamination within a single housing
- Sensus 243 accepts interchangeable orifices and springs for field adjustment
Why Do Facilities Teams Source Pressure Regulators Through Combustion Plus?
Combustion Plus is a factory-authorized representative for Karl Dungs, one of two manufacturer authorizations the company holds. When a regulator fails mid-shift, the difference between same-day resolution and a multi-day outage comes down to who already has the part in stock.
- Factory-authorized Karl Dungs representative with locally stocked FRI series inventory
- Dungs FRI mounts directly to DMV 701, 702, and 703 shutoff valves
- Sensus 243 and 496 cover 3/8 in. through flanged gas train configurations
