Product Description:
Product Features
1. Pilot-Operated Design
This series of solenoid valves employs a pilot-operated working principle, where the pilot valve governs the movement of the main spool. The pilot valve is energized by the solenoid coil, while the main spool moves under the influence of the medium’s pressure difference. This setup enables a low-power solenoid coil to effectively control large flow rates, enhancing energy efficiency and making the valve suitable for applications with higher pressure requirements.
2. Normally Open (NO) Function
The valve is designed to be normally open, meaning it remains open when de-energized, allowing fluid to pass through. Upon energizing the solenoid coil, the valve closes to stop the flow. This normally open feature is ideal for safety-critical scenarios where fluid flow must continue if power fails, such as in cooling systems or emergency venting applications.
3. Single Solenoid Operation
With a single solenoid control mechanism, the valve toggles between open and closed positions by activating or deactivating one solenoid coil. When the coil is de-energized, the valve automatically returns to the normally open position by means of spring force or pressure from the medium, providing straightforward and reliable control.
4. High Flow Capacity
Owing to its pilot-operated structure and streamlined flow path design, this solenoid valve series delivers excellent flow capacity. Flow rates vary by model, ranging from 610 L/min up to 2600 L/min, catering to a wide spectrum of medium to large flow demands.
5. Wide Operating Pressure Range
The valves typically operate within a pressure range of 0.2 MPa to 1.0 MPa (2 to 10 bar), with certain models capable of withstanding pressures up to 1.6 MPa (16 bar). It is important to note that pilot-operated valves need a minimum pressure differential, generally above 0.2 to 0.3 bar, for proper functionality.
6. High-Quality Materials and Sealing
The valve body is constructed from either die-cast aluminum alloy or extruded aluminum, ensuring a lightweight design combined with strength and corrosion resistance. The spool and sleeve options include metal-sealed variants for long service life and soft-sealed types optimized for high flow. Seals are made from NBR or FKM materials, suitable for compressed air and various other media.
7. Low Power Consumption and High Protection Rating
The solenoid coil is designed to consume minimal power, with some models requiring only 1 to 2 watts, contributing to substantial energy savings. Additionally, the valves typically feature an IP65 protection rating, ensuring they are dust-tight and resistant to water jets, making them ideal for use in damp or dusty industrial environments.
8. Flexible Manual Override
A manual override function is included as standard and is usually provided in the form of either a push-button or a twist-lock knob. This feature simplifies tasks such as equipment commissioning, routine maintenance, and emergency manual operation by allowing valve control without electrical input.
9. Diverse Ports and Mounting Options
The valves are compatible with port threads like G1/4, G3/8, or G1/2 British pipe threads, conforming to international standards for seamless integration with various pneumatic systems. Mounting options include both inline piping and sub-base configurations, offering flexible installation tailored to specific system requirements.
Applications:
Industrial Automation Production Lines
These systems are widely implemented in automated assembly lines, material handling setups, and packaging machines. They are primarily designed to control single-acting cylinders, enabling functions such as clamping, positioning, and pushing. Such control solutions are engineered to meet the demands of high-frequency operation and ensure high reliability in industrial environments.
Control of Single-Acting Actuators
The 3/2-way solenoid valve serves as the standard device for managing single-acting pneumatic actuators, including single-acting cylinders, diaphragm valves, and pneumatic grippers. The normally open (NO) type is especially advantageous for safety interlock systems that require the valve to automatically open or close during power outages, making it ideal for emergency venting applications.
Purging and Pressure Relief Systems
In processes that necessitate periodic purging or pressure relief, this valve efficiently controls the on/off flow of compressed air. It plays a critical role in systems such as filter blowback, surface dust removal devices, and safety relief circuits used for air receiver tanks.
Packaging Machinery Applications
These valves are extensively deployed in various packaging equipment including filling machines, sealing machines, labeling units, and blow molding machines. They help control the fast-acting pneumatic actuators, thereby maintaining optimal production cycle times and ensuring packaging precision.
Automotive Manufacturing and Parts Processing
On automotive production lines, the valves are utilized in welding fixtures, painting apparatus, assembly stations, and parts processing machinery. They provide control for pneumatic tooling and auxiliary devices, and are designed to withstand challenges such as oil exposure, vibration, and the need for prolonged service life.
Food and Beverage Production
Suitable for pneumatic systems in food processing equipment, these valves are used in processes like blow molding, filling, and sealing. The selection of sealing materials and lubrication methods adheres strictly to food-grade standards to guarantee safety and hygiene throughout production.
Energy and Environmental Protection Equipment
In environmental protection installations such as thermal power plants, wastewater treatment, and exhaust gas treatment facilities, these valves manage pneumatic control valves and on/off valves. Their function is essential for automating process control and enabling remote operation capabilities.
Special Condition Applications
Certain valve models are designed to operate over a wide temperature range, for instance from –10°C up to +50°C or beyond. In low-temperature environments, it is recommended to use dry air to avoid freezing issues. For environments with explosion-proof requirements, optional explosion-proof coils are available to ensure compliance with safety standards.
