Product Description:
Product Features
1. Pilot-Operated Design
This series of 1/4-inch single-coil solenoid valves generally utilizes a pilot-operated principle. A low-power solenoid coil controls a pilot valve, which in turn uses the medium’s pressure difference to actuate the main spool. This configuration enables a small coil to manage relatively large flow rates efficiently, making it ideal for applications that require frequent switching.
2. Single Coil (Single Solenoid) Control
Featuring a single-coil design, the valve switches states through energizing or de-energizing the solenoid coil. Upon de-energization, a spring mechanism automatically returns the valve to its original position. This simple yet reliable method is perfect for controlling single-acting actuators.
3. Compact Design with Standardized Ports
The valve body incorporates standard 1/4-inch NPT or BSP threaded ports and boasts a compact structure. This small footprint facilitates installation in equipment with limited space, making it suitable for integration within control panels or pneumatic circuits used in various automation devices.
4. High-Quality Body Materials
Valves are available in brass or 316L stainless steel bodies. Brass models provide excellent pressure resistance up to 25 bar and are well-suited for general industrial environments. For more demanding applications such as chemical processing, food industries, or marine uses, stainless steel bodies deliver superior corrosion resistance.
5. Innovative Sealing Technology
These valves incorporate a distinctive sealing method that combines a T-shaped seal with a flexible O-ring. This results in bubble-tight sealing and outstanding protection against dirt ingress. The sealing system is durable enough to withstand millions of operational cycles, ensuring long service life and high reliability.
6. Low Power Consumption and Wide Voltage Range
The solenoid coils are designed for low power consumption, with certain models requiring only between 1.5W and 2.5W, leading to substantial energy savings. They support a variety of voltage options, including DC 24V and AC 220V, making them compatible with PLCs and other automation controllers. With protection ratings up to IP65/IP67, these valves are dust-tight and resistant to water jets, suitable for harsh industrial settings.
7. Fast Response and Long Service Life
These valves provide rapid response times, with opening operations completed within 15 milliseconds and closing within 20 milliseconds. Their design life surpasses 5 million cycles, while some premium models can reach over 100 million cycles, perfectly meeting the needs of high-frequency start-stop applications.
8. Flexible Manual Override
A manual reset device or manual operator is included as a standard feature, facilitating equipment commissioning, routine maintenance, and emergency manual operation. This functionality allows the valve to be operated without electrical signals, thereby enhancing overall system safety and ease of maintenance.
9. Multiple Mounting Options
The valves are versatile in installation, supporting direct inline piping as well as mounting directly onto pneumatic actuators via standard NAMUR interfaces. There are no restrictions on installation orientation, providing flexibility to position the valves according to available site space.
Applications:
Industrial Automation Production Lines
These devices are extensively applied in automated production environments such as packaging machines, assembly systems, and material handling setups. They play a crucial role in controlling single-acting cylinders, pneumatic grippers, and various actuators for essential operations including clamping, positioning, and pushing.
Pneumatic Control Systems
Serving as fundamental control elements within pneumatic setups, these components are utilized for switching and directional control in air compressor units, pneumatic tools, and compressors. Their 1/4-inch port size is ideal for small to medium-sized pneumatic circuits, offering typical flow rates between 700 and 860 liters per minute at 6 bar pressure. This specification fulfills the operational requirements of most pneumatic actuators.
Dust Collection and Environmental Protection Equipment
In pulse jet dust collection systems, these valves manage the rapid release of compressed air necessary for the online cleaning of filters. Additionally, they are employed in valve automation processes within environmental protection facilities, including wastewater treatment plants and exhaust gas purification systems.
Energy and Chemical Industries
These products are well-suited for applications in the energy sector, such as controlling boiler feed valves, gas pipeline safety shut-off mechanisms, and burner regulation. Certain models come with ATEX and IEC Ex explosion-proof certifications, ensuring safe operation in hazardous environments like petrochemical plants and propane management systems.
Food, Beverage, and Life Sciences
Stainless steel versions meet stringent sanitary standards, making them suitable for industries requiring high levels of cleanliness, such as food processing, beverage bottling, and pharmaceutical manufacturing. Available sealing materials like EPDM or Viton ensure compatibility with food-grade substances and accommodate rigorous cleaning and sanitization procedures.
Automotive Manufacturing and Parts Processing
Within automotive production lines, these components are used across welding fixtures, painting apparatus, and assembly stations to control pneumatic tools and auxiliary systems. Low-power variants are particularly advantageous for integration with PLC control systems, thereby addressing the automotive sector's demands for dependable performance and efficient cycle times.
Special Condition Applications
Hazardous Locations:
Models certified with ATEX, IEC Ex, UL, and other international explosion-proof standards are designed for use in flammable and potentially explosive environments such as petrochemical and gas industries.
Extreme Cold Environments:
Certain versions operate reliably in low-temperature conditions down to –60°C, making them ideal for cold storage facilities, outdoor use, and other applications requiring cold resistance.
High-Temperature Media:
Specialized models withstand high temperatures up to 99°C (210°F), suitable for steam and hot water systems.
Corrosive Media:
Combining stainless steel bodies with corrosion-resistant seals, these units effectively handle mildly acidic, alkaline, and some corrosive fluids.
