Product Description:
Product Features
1. Pilot-Operated Design
This series of solenoid valves utilizes a pilot-operated mechanism whereby the pilot valve directs the movement of the main spool. The pilot valve is activated by the solenoid coil, and the main spool responds to the pressure differential of the medium. This design enables a low-power solenoid coil to regulate the on/off function for large flow rates, enhancing energy efficiency and suitability for higher pressure scenarios.
2. Normally Open (NO) Function
The valves are normally open at rest, allowing the medium to flow freely when de-energized. When the solenoid coil is energized, it actuates the valve to close and stops the flow. This normally open feature is ideal for safety-critical applications where maintaining flow during power failure is essential, such as in cooling or emergency venting systems.
3. Single Solenoid Operation
These valves operate with a single solenoid coil controlling both opening and closing actions. Upon de-energizing, the valve automatically reverts to the normally open state through the action of a spring or medium pressure, ensuring simple and dependable performance.
4. High Flow Capacity
Thanks to the pilot-operated design and an optimized flow path, the valves provide outstanding flow capacities. Depending on specific models, flow rates range from 610 liters per minute up to 2600 liters per minute, accommodating various medium to large flow demands.
5. Wide Operating Pressure Range
These solenoid valves typically operate within a pressure range of 0.2 MPa to 1.0 MPa (2–10 bar), with certain models capable of functioning at pressures as high as 1.6 MPa (16 bar). It is important that the minimum pressure differential, generally above 0.2 to 0.3 bar, is maintained for proper valve operation.
6. High-Quality Materials and Sealing
The valve bodies are manufactured from die-cast aluminum alloy or aluminum extrusion, providing lightweight yet strong construction with good resistance to corrosion. Spools and sleeves come in either metal-sealed versions for extended durability or soft-sealed types optimized for high flow. Seals are crafted from NBR or FKM materials, suitable for compressed air and a variety of other media.
7. Low Power Consumption and High Protection Rating
The solenoid coils consume minimal power, with some models requiring as little as 1 to 2 watts, contributing to significant energy savings. Additionally, the valves have a protection rating commonly at IP65, which ensures they are dust-tight and protected against water jets, making them appropriate for usage in humid or dusty industrial environments.
8. Flexible Manual Override
Each valve includes a manual override feature, usually in the form of a push-button or twist-lock knob. This allows for easy equipment commissioning, routine maintenance, or emergency manual operation without the need for electrical input.
9. Diverse Ports and Mounting Options
Port threads generally conform to international standards, including G1/4, G3/8, and G1/2 British pipe threads, facilitating effortless integration with various pneumatic systems. Moreover, the valves support both inline piping and sub-base mounting options to provide flexibility depending on the system configuration.
Applications:
Industrial Automation Production Lines
These systems are extensively utilized in a variety of automated assembly lines, material handling setups, and packaging machinery. They primarily function to control single-acting cylinders for operations such as clamping, positioning, and pushing. This ensures the capability to meet the high demands of frequent and reliable control in industrial environments.
Single-Acting Actuator Control
A 3/2-way solenoid valve is commonly employed to manage single-acting pneumatic actuators, including single-acting cylinders, diaphragm valves, and pneumatic grippers. The normally open (NO) design is especially advantageous in safety interlock systems where the valve must automatically open or close during power outages, such as in emergency venting applications.
Purging and Pressure Relief Systems
In processes that require regular purging or pressure relief, this type of valve serves to regulate the on/off flow of compressed air. It plays a crucial role in systems like filter blowback, surface dust removal devices, and safety relief circuits within air receiver tanks, ensuring consistent and safe operational performance.
Packaging Machinery
These valves are widely applied in various packaging machines such as filling, sealing, labeling, and blow molding equipment. They facilitate the swift movement of pneumatic actuators, thereby maintaining efficient production cycle times and achieving precise packaging results.
Automotive Manufacturing and Parts Processing
On automotive production lines, these components are used in welding fixtures, painting stations, assembly points, and parts processing machinery. They control pneumatic tooling and auxiliary devices, demanding features like oil resistance, vibration tolerance, and extended service life to withstand harsh industrial conditions.
Food and Beverage Production
Suitable for pneumatic control in food processing equipment, these valves support operations such as blow molding, filling, and sealing. The choice of sealing materials and lubricants complies with food-grade standards, ensuring the safety and hygiene of the production environment.
Energy and Environmental Protection Equipment
In environmental protection and energy sectors, these valves are utilized within valve control systems for facilities like thermal power plants, wastewater treatment centers, and exhaust gas cleaning stations. They drive pneumatic control and on/off valves to enable automated process management and remote operation capabilities.
Special Condition Applications
Certain valve models are designed to operate effectively across wide temperature ranges, for instance from –10°C to +50°C or beyond. In colder environments, the use of dry air is recommended to prevent freezing. Additionally, for areas requiring explosion-proof measures, specially designed explosion-proof coils can be installed to ensure compliance with safety regulations.
