Product Description:
Product Features
1. Pilot-Operated Design
This range of solenoid valves employs a pilot-operated mechanism where a pilot valve manages the movement of the main spool. The pilot valve is driven by a solenoid coil, while the main spool is actuated through the pressure difference of the working medium. This setup enables a low-power solenoid coil to control the opening and closing of valves with large flow rates, enhancing energy efficiency and suitability for higher pressure environments.
2. Normally Open (NO) Function
The valves feature a normally open configuration, meaning they remain open when not energized, allowing fluid flow. Upon energizing the solenoid coil, the valve closes and stops the flow. This characteristic is ideal for safety-critical applications where it's essential to maintain flow during power outages, such as in cooling or emergency venting systems.
3. Single Solenoid Operation
Operating with a single solenoid coil, the valve transitions between open and closed states by energizing or de-energizing this coil. After power is cut, the valve returns to its normally open position automatically via internal spring force or medium pressure, ensuring straightforward and dependable control.
4. High Flow Capacity
Thanks to the pilot-operated design and optimized internal flow paths, these solenoid valves provide excellent flow capacities. Depending on the specific model, flow rates can range from 610 liters per minute up to 2600 liters per minute, catering to a variety of medium to high flow requirements.
5. Wide Operating Pressure Range
The valves operate effectively across a pressure range generally from 0.2 MPa to 1.0 MPa (2 to 10 bar), with some versions capable of handling pressures as high as 1.6 MPa (16 bar). It's crucial to maintain a minimum pressure differential—typically between 0.2 and 0.3 bar—for correct valve operation.
6. High-Quality Materials and Sealing
Constructed from die-cast aluminum alloy or aluminum extrusion, the valve bodies offer a combination of light weight, strength, and corrosion resistance. The spool and sleeve can be configured with either metal seals for long lifespan or soft seals for enhanced flow performance. Sealing materials include NBR and FKM, making these valves compatible with compressed air and various fluids.
7. Low Power Consumption and High Protection Rating
The solenoid coils are designed for low power consumption, with some models requiring only 1 to 2 watts, which contributes to significant energy savings. Additionally, the valves have an IP65 protection rating, ensuring they are dust-tight and resistant to water jets, making them reliable in moist or dusty industrial environments.
8. Flexible Manual Override
Each valve includes a manual override mechanism, commonly available as a push-button or twist-lock knob. This feature simplifies equipment setup, maintenance, and allows manual valve operation during emergencies without depending on electrical control signals.
9. Diverse Ports and Mounting Options
The valve ports are typically equipped with G1/4, G3/8, or G1/2 British Standard Pipe threads, adhering to international standards for seamless integration with various pneumatic components. The valves support both inline piping installations and sub-base mounting configurations, offering flexibility to accommodate different system setups.
Applications:
Industrial Automation Production Lines
Industrial automation components are extensively utilized across various automated assembly lines, material handling systems, and packaging machinery. They primarily manage single-acting cylinders to perform crucial functions such as clamping, positioning, and pushing. These systems are designed to fulfill the requirements of high-frequency operation and dependable control performance.
Single-Acting Actuator Control
The 3/2-way solenoid valve serves as the fundamental element for controlling single-acting pneumatic actuators, including single-acting cylinders, diaphragm valves, and pneumatic grippers. Its normally open (NO) configuration is especially advantageous in safety interlock scenarios, where the valve must automatically open or close in the event of power failure, such as during emergency venting procedures.
Purging and Pressure Relief Systems
In industrial processes that require regular purging or pressure relief, these valves effectively regulate the on/off operation of compressed air. They are integral to applications like filter blowback mechanisms, surface dust removal devices, and safety relief circuits for air receiver tanks.
Packaging Machinery
These valves find widespread usage in various packaging equipment, including filling, sealing, labeling, and blow molding machines. By controlling the swift movement of pneumatic actuators, they help maintain optimized production cycle times and ensure precise packaging quality.
Automotive Manufacturing and Parts Processing
In automotive production lines, pneumatic control components are employed in welding fixtures, painting systems, assembly stations, and parts processing machine tools. These applications demand components that can withstand oil exposure, vibrations, and offer extended durability for reliable operation.
Food and Beverage Production
Pneumatic control systems tailored for the food processing industry are used in blow molding, filling, and sealing operations. Selecting appropriate sealing materials and lubrication methods that comply with food-grade standards is essential to maintain safety and hygiene throughout the production cycle.
Energy and Environmental Protection Equipment
Valve control systems in environmental protection facilities, such as thermal power plants, wastewater treatment plants, and exhaust gas treatment units, utilize these pneumatic valves. They facilitate the automation of process controls and enable remote operation by managing pneumatic control valves and on/off valves efficiently.
Special Condition Applications
Certain valve models are engineered to operate across wide temperature ranges, for example, from –10°C up to +50°C or beyond. In low-temperature environments, it is advisable to use dry air to avoid freezing issues. Additionally, for areas requiring explosion-proof equipment, specialized explosion-proof coils are available to comply with stringent safety regulations.
