Advantages of Stiefel’s Solenoid Valves

Fast-Acting and Energy-Efficient Designs

Stiefel’s solenoid valves incorporate magnetic latching technology which reduces idle power use by 85% when compared to earlier models. Actuation of emergency shutoff is vital in safety applications like hydrogen fuel systems which require fast (<30 ms open/close) actuation. Our valves have met OSHA standards at a Saudi Arabian LPG storage refinery with 20ms fail-safe closure. A rural Indian biomass power plant was able to save with less than 3W of power consumption. Users are notified of potential issues such as overheating coils and debris accumulation before failure through our self-diagnostic modules. modules notify users of potential problems like coil overheating or debris buildup prior to failure.

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

Now, with our smart valves, sensors also measure and monitor performace metrics like coil temperature, actuation speed, and leakage rate. This information was used by a Dutch dairy plant to predict seal replacements which reduced unplanned downtime by 35% and optimized maintenance expenditure by 20%.
Certification and Compliance on A Global Scale

Certification and Compliance on A Global Scale

Our valves surpass various industry requirements with CE, ATEX, UL, CSA and FDA certifications. Notable examples are our medical-grade valves used in oxygen systems in US hospitals and industrial valves manufactured in compliance with machine directive EU 2006/42/EC in production plants around the globe.
