Product Description:
Product Features
1. Pilot-Operated Design
This range of 1/4-inch single-coil solenoid valves primarily uses a pilot-operated mechanism. In this design, a low-power solenoid coil controls a pilot valve, which then leverages the medium's pressure difference to actuate the main spool. This approach enables a small coil to manage relatively large flow rates, making it ideal for applications that require frequent switching.
2. Single Coil (Single Solenoid) Control
Equipped with a single-coil configuration, the valve operates by energizing and de-energizing the solenoid coil. Once de-energized, the valve automatically returns to its original position through spring force. This feature ensures straightforward and reliable control, perfectly suited for single-acting actuator uses.
3. Compact Design with Standardized Ports
The valve body includes standardized 1/4-inch NPT or BSP threaded ports, coupled with a compact design that allows for installation in constrained spaces. Its small footprint makes it an excellent choice for integration into control panels or pneumatic circuits within a variety of automated systems.
4. High-Quality Body Materials
Available in brass or 316L stainless steel, the valve body’s material options cater to different environments. Brass provides excellent pressure resistance up to 25 bar and suits general industrial conditions, whereas stainless steel offers enhanced corrosion resistance, fitting for harsh environments such as chemical processing, food-grade applications, and marine use.
5. Innovative Sealing Technology
Featuring a unique sealing system that combines a T-shaped seal with a flexible O-ring, these valves achieve bubble-tight sealing along with superior resistance to dirt ingress. Designed to endure millions of operational cycles, this sealing structure ensures extended durability and dependable performance.
6. Low Power Consumption and Wide Voltage Range
The solenoid coil is engineered for low energy consumption, with some models requiring as little as 1.5W to 2.5W, which helps reduce energy costs. Multiple voltage options are offered, including DC 24V and AC 220V, making the valves compatible with PLCs and various automation control systems. Protection ratings up to IP65/IP67 provide dust-tightness and resistance to water jets, making them suitable for demanding industrial environments.
7. Fast Response and Long Service Life
These valves boast rapid response times, opening within 15 milliseconds or less, and closing within 20 milliseconds. Their design life surpasses 5 million cycles, and some high-end models can achieve over 100 million cycles, perfectly catering to applications requiring high-frequency start-stop operations.
8. Flexible Manual Override
The product is equipped with a manual reset mechanism or manual operator as standard, which aids in equipment commissioning, maintenance, and emergency manual operation. This feature enables valve operation without an electrical signal, enhancing overall system safety and ease of maintenance.
9. Multiple Mounting Options
These valves can be installed directly in inline piping or mounted onto pneumatic actuators using standard NAMUR interfaces. There are no constraints regarding installation orientation, allowing flexible positioning to fit various site layouts and space conditions.
Applications:
Industrial Automation Production Lines
Pneumatic control systems are extensively utilized in automated production lines including packaging machinery, assembly equipment, and material handling systems. They are instrumental in operating single-acting cylinders, pneumatic grippers, and various actuators to perform functions such as clamping, positioning, and pushing.
Pneumatic Control Systems
Serving as essential control components in pneumatic systems, these devices enable switching and directional control within air compressor stations, pneumatic tools, compressors, and other machinery. With a 1/4-inch port size, they are ideally suited for small to medium pneumatic circuits. Their typical flow rates range from 700 to 860 liters per minute at 6 bar pressure, fulfilling the operational needs of most pneumatic actuators.
Dust Collection and Environmental Protection Equipment
In pulse jet dust collector systems, these valves manage the rapid release of compressed air needed for online filter cleaning. Additionally, they are employed in the automation of valves used in environmental protection facilities, including wastewater treatment plants and exhaust gas treatment systems.
Energy and Chemical Industries
These pneumatic components are well-suited for energy sector applications such as boiler feed valve control, gas pipeline safety shut-off, and burner management. Certain models come with ATEX and IEC Ex explosion-proof certifications, ensuring safe operation in hazardous environments like petrochemical plants and propane control systems.
Food, Beverage, and Life Sciences
For industries requiring high sanitary standards, models with stainless steel bodies fulfill stringent cleanliness requirements. They are commonly used in food processing, beverage filling, and pharmaceutical equipment. Furthermore, sealing options like EPDM or Viton allow compatibility with food-grade media and facilitate cleaning and sanitization processes.
Automotive Manufacturing and Parts Processing
Pneumatic control devices are employed in welding fixtures, painting machinery, and assembly stations within automotive manufacturing lines. They govern pneumatic tooling and auxiliary equipment efficiently. Low-power models integrate seamlessly with PLC systems, meeting the automotive industry's stringent demands for reliability and quick cycle times.
Special Condition Applications
Hazardous Locations
Models certified with ATEX, IEC Ex, UL and other international explosion-proof standards are ideal for use in flammable and explosive environments, such as those found in petrochemical and gas industries.
Extreme Cold Environments
Some variants operate reliably in extremely low temperatures down to –60°C, making them suitable for cold storage facilities, outdoor installations, and other low-temperature scenarios.
High-Temperature Media
High-temperature resistant models are designed for steam and hot water applications, capable of handling media temperatures up to 99°C (210°F).
Corrosive Media
Combining stainless steel bodies with corrosion-resistant seals, these devices are capable of controlling mildly acidic, alkaline, and certain corrosive fluids, expanding their usability in harsh chemical environments.
