Advantages of Stiefel’s Solenoid Valves

Custom Solutions For Specialized Applications

Some of the areas we cover are strapping cryogenic logistics, medical gas systems, and semiconductor high-purity manufacturing which are very specific environments. Our anti-stiction coatings on ceramic armature valves reliably operate in ultra-low temperatures, -196 degree celcius for liquid nitrogen systems. For the phramaceutical industry, we offer FDA-compliant models with electropolished surfaces which meets hygiene standards. Our valves are designed specifically for dual fuel burners and have independent gas and oil pathways which enables seamless switching of fuel on resort boilers in the Caribbean that operate at <=50mg/Nm^3 NOx emissions.

Designed to withstand harsh environments, Stiefel’s solenoid valves are manufactured from 316 stainless steel and hastelloy, both of which resist corrosion, making them suitable for waste incineration boilers where acidic flue gases are present. The double-seal configuration (primary PTFE + secondary metal-to-metal) provides additional protective redundancy from leak exposure, and is critical when industrial burners use hydrogen gas as a fuel source. A customer with a chemical plant using our valves in their boiler system reported there was no leakage for 4 years of constant operation, thermally cycling daily from 25°C to 180°C. Every valve is subjected to 100% pressure testing (1.5x rated pressure) and helium leak detection which ensures unparalleled quality control for the manufacturer.

Frequently Asked Questions

Steam Systems Require Reliable Valves

For three years now, Stiefel’s solenoid valves have been a critical component of our hospital’s steam sterilization cycle. Their 316SS bodies stand up to the aggressive cleaning damage associated with hospital grade sterilization while the steam flow control ensured by the fast actuation <80ms is unparalleled. Thanks to the easy-to-replace modular components and robust screw design, we have seen a reduction in maintenance calls by 70%.

Stiefel’s commitment to material innovation is evident in components such as silicon carbide (1,400°C resistant) coils and ultra low friction DLC diamond-like carbon coatings. These materials provide 50% reduced wear in high-cycle applications for paint booth valves in German automotive plants which have performed for over 5million cycles.
Predictive Maintenance With IoT

Predictive Maintenance With IoT

Additional to our smart valves, sensors measure and monitor performance metrics such as temperature of coil, speed and leakage rate of actuation. A Dutch dairy plant used this information to accurately forecast seal replacements resulting in a 35% decrease in unplanned downtime and 20% optimization of maintenance expenditure.
Certification and Compliance on A Global Scale

Certification and Compliance on A Global Scale

Our valves soar many industry standards with CE, ATEX, UL, CSA and FDA certicates. Exemplified by our medical-grade valves in US hospitals oxygen systems and industrial valves complying with machine directive EU 2006/42/EC in manufacturing facilities worldwide.
