Product Features
Pilot-Operated Design
This series of 1/4-inch single-coil solenoid valves operates based on a pilot-operated principle. A low-power solenoid coil controls the pilot valve, which utilizes the medium's pressure difference to actuate the main spool. This approach enables a small coil to manage relatively large flow rates efficiently, making the valves ideal for applications requiring frequent switching.
Single Coil (Single Solenoid) Control
Featuring a single-coil configuration, the valve switches by energizing and de-energizing one solenoid coil. Once de-energized, the valve returns automatically by spring force, ensuring straightforward and reliable operation. This makes it well-suited for use with single-acting actuators.
Compact Design with Standardized Ports
The valve body is equipped with standard 1/4-inch NPT or BSP threaded ports. Its compact design allows installation in tight spaces, making it an excellent choice for integration within control panels or pneumatic circuits found in various automation devices.
High-Quality Body Materials
Available in brass or 316L stainless steel, the valve body materials cater to different industrial needs. Brass offers strong pressure resistance up to 25 bar, suitable for general industrial environments, while stainless steel provides enhanced corrosion resistance for more demanding conditions, such as chemical processing, food industries, and marine applications.
Innovative Sealing Technology
These valves utilize a distinctive sealing system that combines a T-shaped seal with a flexible O-ring. This design achieves bubble-tight sealing and exceptional resistance to dirt. It supports millions of operational cycles, ensuring long-lasting service life and high reliability.
Low Power Consumption and Wide Voltage Range
Equipped with low-power solenoid coils, some models consume as little as 1.5W to 2.5W, offering significant energy efficiency. Multiple voltage options are available, including DC 24V and AC 220V, ensuring compatibility with PLCs and other automation systems. Protection ratings can reach IP65 or IP67, providing resistance against dust and water jets, suitable for harsh industrial environments.
Fast Response and Long Service Life
The valves demonstrate rapid response times, with opening times of 15 milliseconds or less and closing times within 20 milliseconds. They are designed for durability, with a lifespan exceeding 5 million cycles, and some premium models can surpass 100 million cycles, meeting the requirements of high-frequency start-stop operations.
Flexible Manual Override
Included as a standard feature is a manual reset device or manual operator, which facilitates commissioning, maintenance, and emergency manual control. This allows the valve to be operated without electrical power, enhancing overall system safety and ease of maintenance.
Multiple Mounting Options
These valves support installation directly in inline piping and can also be mounted on pneumatic actuators using standard interfaces such as NAMUR mounting. There are no restrictions on installation orientation, offering flexible placement tailored to the spatial requirements of the site.
Applications:
Industrial Automation Production Lines
Pneumatic control components find extensive application in automated production lines, including packaging machinery, assembly equipment, and material handling systems. They are essential for managing single-acting cylinders, pneumatic grippers, and various actuators that perform critical functions such as clamping, positioning, and pushing.
Pneumatic Control Systems
Serving as fundamental control elements in pneumatic circuits, these devices are widely utilized for switching and directional control within air compressor stations, pneumatic tools, and compressors. Their 1/4-inch port size makes them apt for small to medium pneumatic systems, offering typical flow rates between 700 and 860 liters per minute at 6 bar pressure, thereby fulfilling the operational requirements of most pneumatic actuators.
Dust Collection and Environmental Protection Equipment
In pulse jet dust collector systems, these valves regulate the rapid release of compressed air to enable in-service filter cleaning. Furthermore, they are integral to valve automation in environmental protection sectors such as wastewater treatment and exhaust gas purification facilities.
Energy and Chemical Industries
These components are well-suited for use in energy-related equipment, including boiler feed valves, gas pipeline safety shut-off mechanisms, and burner control systems. Certain models carry ATEX and IECEx explosion-proof certifications, ensuring safe operation in hazardous environments, including petrochemical plants and propane handling applications.
Food, Beverage, and Life Sciences
Models with stainless steel construction comply with stringent sanitary standards, making them ideal for high cleanliness applications like food processing, beverage filling lines, and pharmaceutical manufacturing equipment. Additionally, sealing materials such as EPDM or Viton are available to accommodate food-grade substances and support thorough cleaning and sanitization routines.
Automotive Manufacturing and Parts Processing
In automotive production environments, these valves are employed within welding fixtures, painting systems, and assembly stations to control pneumatic tools and auxiliary devices. Low-power variants are particularly advantageous when integrated with PLC control systems, addressing the automotive industry’s stringent demands for high reliability and efficient cycle times.
Special Condition Applications
Hazardous Locations: Models certified by ATEX, IECEx, UL, and other international explosion-proof standards are designed for safe use in combustible atmospheres such as those found in petrochemical and gas processing operations.
Extreme Cold Environments: Certain valve models maintain normal functionality at temperatures as low as –60°C, making them suitable for cold storage facilities, outdoor deployments, and other applications subject to severe cold conditions.
High-Temperature Media: Specially designed high-temperature models can handle steam and hot water systems with media temperatures reaching up to 99°C (210°F).
Corrosive Media: Valves featuring stainless steel bodies paired with corrosion-resistant seals are capable of controlling mildly acidic or alkaline fluids, as well as select corrosive media, thereby extending their usability in challenging chemical environments.
