Advantages of Stiefel’s Solenoid Valves

Fast-Acting and Energy-Efficient Designs

Stiefel’s solenoid valves utilize magnetic latching technology which reduces standby power consumption by 85%, when compared to traditional models. Emergency shutoff actuation is critical for safety applications like hydrogen fuel systems, requiring fast (<30 ms opening/closing) actuation. Our valves met OSHA requirements at a Saudi Arabian refinery for LPG storage with a 20ms fail-safe closure. A rural Indian biomass plant benefitted from under 3W power consumption. Users are alerted of potential failures such as overheating coils or debris accumulation with our self-diagnostic modules on.

Meeting international standards, Stiefel’s CE certified solenoid valves are tailored for customers from the EU and other regions with stricter requirements. Their explosion proof types (EEx d IIC T6) have flameproof enclosures and also use epoxy-coated coils, making them appropriate for gas burners in pharmaceutical and food processing plants. Our CE-certified valves helped a Spanish winery with a boiler system needing dependable gas control while complying with the EU’s 2006/42/EC Machinery Directive. The valves feature compact dimensions (1.5” NPT ports), and the IP67 rating is resistant to water jets and dust, protecting outdoor kiln installations.

Frequently Asked Questions

Can Stiefel’s solenoid valves manage aggressive chemicals or gases?

Yes, Stiefel’s valves are made with chemically inert PEEK and Hastelloy materials. An example is a Japanese electronic plant using PEAK valves in evaporating acid systems with PTFE seals and ceramic discs that outlast standard elastomers by 3x. For hydrogen applications, our valves are nickel plated brass with non-ignition riser copper coils which meets ISO 19880-5 safety standards.

Customer Feedback

Thomas B.
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%.

Advanced Material Sciences

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.
