Advantages of Stiefel's Boiler Parts

Customizable Solutions for Diverse Boiler Applications

Stiefel specializes in tailor made parts to fully service an operation’s diverse needs. For waste-to-energy plants, we offer flue gas processing valves for boilers, which increases the part life from 6 months to three years thanks to its Hastelloy sealing. Compact solenoid valves (1.5” NPT ports) for commercial kitchens can be retrofitted, thus cutting installation time by 30%. Seeing the need for global compatibility, we provide 24V DC/230V AC dual voltage control modules, like the one used by a Caribbean resort in their solar powered boiler system that had to seamlessly work with local grid controls.

To ensure the safety of the boiler, these valves contain double block and bleed (DBB) configurations for maintenance isolation, along with self-cleaning mechanisms that avoid debris accumulation. For the steam boiler system in a hospital in the U.S., our valves automated helium leak testing with corrosion resistant hastelloy internals, which previously resulted in a dozen leaks annually, to now zero. The valves’ 4–20mA feedback control loop compatibility with boiler control systems allows PLCs integration for automatic load adjustments.

Frequently Asked Questions

Does Stiefel have the capability to manufacture custom boiler parts tailored to more obscure boiler models?

Indeed, they do. We've partnered up with a European boiler manufacturer to develop a bespoke control module featuring integrated IoT sensors, which has slashed their product development duration by thirty percents. These legs for non-standard boilers or specialized seals for cryogenic tasks can be achieved thanks to close collaboration with the engineering teams. We are able to meet all requests, custom or otherwise, in a 6-8 week timeframe.

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.
