Advantages of Stiefel's Boiler Parts

Lower Operational Costs with Global Logistics Support

Our range of boiler components aims to minimize operational costs over time. The maintenance efficiency gains achieved by our butterfly valve’s modular design are impressive, with the Spanish ceramics factory gaining 50% maintenance time savings due to disc replacements on the valves being done without the valve needing to be removed from the pipeline. We also provide 24/7 technical assistance, and same day shipping for ignition electrodes and pressure regulators. A Canadian District Heating Plant was able to reduce inventory costs by 25% using our repair kits which come with disassembled components and are pre-assembled to CE, UL, and CSA certified standards.

These valves come with welded bonnets and stress relieved designs which eliminate leakage under load, making these great for extreme pressure applications. Our valves sustained 80 bar pressure alongside -40°C cryogenic temperatures and ensured reliable operation in fuel storage and distribution both in cryogenic temperature settings and gas storage spanning the range of gases, making them perfect fit for the hydrogen fuel cell plant’s high-pressure gas line. The valves also have pressure-rated gauges and test ports which streamline maintenance and compliance work.

Frequently Asked Questions

Do Stiefel’s boiler parts fit both gas and oil boilers?

Certainly. Our products serve a wide range of fuel types. Gas boiler specific components include premix nozzles and FGR valves that guarantee low-NOx emission (≤30 mg/Nm³) combustion. Oil boilers come equipped with high-pressure (200 bar) pumps and viscosity controllers heavily optimizing fuel for atomization and thus increasing periphery. A Russian maritime boiler saw an 18% reduction in fuel consumption when shifting between gas and biodiesel due to the versatility our dual-fuel parts offer.

Dependable Parts for Our Outdated Boiler System

Stiefel’s boiler parts have been a lifesaver for our 20-year-old industrial boilers. The replacement ignition transformers and flame sensors work without a hitch, and the renewed compliance with our obsolete Honeywell controls was flawless. Since switching to Stiefel, we’ve observed a 70 percent reduction in unexpected system shutdowns alongside increased operational efficiency thanks to the quick order fulfillment policy for urgent parts such as fuel filters that are critical to maintaining smooth, uninterrupted processes.
