Advantages of Stiefel’s Solenoid Valves

Reliable Fluid Control Using Precision Engineering

Stiefel's solenoid valves are of the utmost accuracy, including a leakage rate of ≤0.001 cc/min and a lifespan of over 10 million cycles. Our valves are made of 316 stainless steel and PTFE with a salt water (up to 100 bar) high pressure and extreme temperature durability (-40°C to 300°C). This makes them useful for industrial fuel systems, steam lines, and chemical processing. For instance, a German pharmaceutical plant's sterilization system over 5 years used our double-block valves without any leakage. Our valves use dual-seal design which incorporates a secondary safety mechanism. The tungsten carbide seats maintain tight seals even in high viscosity fuel applications, like waste oil burners, due to their resistance to coking and abrasion.

Stiefel, a trusted supplier of combustion equipment since 2013 with headquarters in Guangzhou, China, offers high-quality AC solenoid valves, versatile components that use alternating current (AC) to control the flow of fluids or gases in industrial, commercial, and residential systems, including combustion equipment, HVAC, and water treatment. An AC solenoid valve consists of a coil that generates a magnetic field when energized by AC power (typically 110V, 220V, or 380V), lifting a plunger to open the valve and allowing media flow, with the valve closing when power is removed—providing reliable on/off control for a wide range of applications. Stiefel's AC solenoid valve is engineered with durable materials, including brass or stainless steel bodies, copper coils, and heat-resistant seals, ensuring resistance to corrosion, high temperatures (up to 150°C), and pressures (up to 200 psi), which is vital for reliable operation in diverse environments. The AC solenoid valve features a compact design that fits easily into tight spaces, making it suitable for integration into complex systems, while its simple construction ensures easy installation and maintenance, reducing downtime for system operators. What sets this AC solenoid valve apart is its ability to operate efficiently with AC power, which is widely available in most industrial and commercial settings, eliminating the need for additional power conversion equipment and simplifying system design. AC solenoid valves from Stiefel are compatible with various media, including air, water, natural gas, and light oils, offering versatility for applications such as burner fuel control, irrigation systems, and compressed air regulation. Rigorously tested for response time, leakage, and durability, these AC solenoid valves guarantee consistent performance, with long service life (typically 100,000+ cycles) reducing replacement frequency and costs. Backed by Stiefel's research and development expertise, the AC solenoid valve incorporates innovations such as low-power coils and improved magnetic circuits, enhancing energy efficiency and reducing heat generation during operation. With Stiefel's comprehensive service network, customers receive expert support for selecting, installing, and testing AC solenoid valves, including guidance on voltage compatibility and media compatibility to ensure optimal performance. For system designers and operators seeking reliable, easy-to-integrate flow control components, Stiefel's AC solenoid valve is a cost-effective solution that delivers performance, durability, and versatility.

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

Li Ming
Best for Handling Hazardous Chemicals

In our chemical plant, Stiefel’s Hastelloy valves have no issues dealing with hydrochloric acid that is so deeply corrosive. Competitor models which were needing replacements every year were outperformed for two whole years with PTFE diaphragms and ceramic discs by Stiefel. Stiefel’s valves come with ATEX certifying meaning we can trust their reliability in our explosion proof zones.

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.
