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.

Flowing up to 500 m³/h gas, these valves have piston actuators and utilize full-bore designs which are ideal for high-volume applications. With our 4” valves at a Russian district heating plant, we achieved a 15% reduction in energy loss from pressure drops, translating to $22,000 saved annually in pumping costs. The NACE MR0175 sour gas compliant flanges and valves add ease to installation within massive industrial infrastructures whereas the sour gas compliant valves strengthen the installation’s network.

Frequently Asked Questions

In what ways does Stifel protect and enhance the lifespans of boiler parts with respect to high temperatures?

On our part, we apply Inconel, tungsten carbide, and ceramic coatings to these structures. At a powerplant in the U.K, we've had success with spiral fin heat exchangers. They not only possess ceramic coatings but also resist sulfuric acid corrosion found in high sulfur gas boilers. We've maintained 92 percentage thermal efficiency over a decade. Precession platinum rhodium tip ignition electrodes sustain over ten thousand cycles at a staggering 1,400 degrees centigrade. These outperform stainless steel electrode alternatives deemed ‘standard’ by thrice for industrial furnaces.

Easier Maintenance Saves Time and Money with Stiefel

Stiefel also helps us cut expenses with their readily available inventory. Construction managers have a lot on their plate; I focus on multiple commercial buildings and the value Stiefel’s components brings. Their solenoid valves and control panels are equally as good as OEM parts, but at half the price. For commercial contracts, bulk discounts have saved us over $10,000 annually. Restocking is easy with the online ordering system.

Enhanced Compatibility with Hydrogen

Enhanced Compatibility with Hydrogen

Stiefel’s hydrogen-ready valves assist in the ongoing energy transition. Specifically engineered materials and design withstands the rigor of safety and reliability testing required in pure H₂ and blended fuel systems. Our valves are utilized in fuel cell buses in a German hydrogen mobility project – rest assured leak-proof performance and compliance with the EU’s Hydrogen Strategy is achieved.
IoT-Managed Predictive Maintenance Smart Valves

IoT-Managed Predictive Maintenance Smart Valves

Our smart valves contain sensors that monitor actuation speed, temperature, and leakage, facilitating proactive maintenance. A U.S. natural gas pipeline operator reduced unplanned downtime by 40% using this data, optimizing maintenance schedules and saving $15,000 annually.
Sustainability and International Compliance

Sustainability and International Compliance

With CE, ATEX, UL, and FDA certified, our valves are trusted globally across regulated industries. The ability to utilize renewable gases while achieving energy efficiency aids in the broader fight for sustainability like the UN’s SDG 7 for Affordable and Clean Energy.
