Product Description:
Product Features
1. Pilot-Operated Design
This range of solenoid valves utilizes a pilot-operated principle, wherein the pilot valve governs the main spool’s movement. The pilot valve is actuated by a solenoid coil, while the main spool responds to the medium’s pressure difference. Such a design enables a low-power solenoid coil to regulate the on/off switching of large flow volumes, enhancing energy efficiency and suitability for higher pressure environments.
2. Normally Open (NO) Function
The valve is normally open by default, which means it allows medium flow when de-energized. When energized, the solenoid coil activates to close the valve, stopping the flow. This normally open feature is ideal for safety-related scenarios where medium flow must be maintained during power outages, such as in cooling or emergency venting systems.
3. Single Solenoid Operation
Operating with a single solenoid coil, the valve smoothly toggles between open and closed states by energizing or de-energizing the coil. Upon de-energization, the valve automatically reverts to its normally open position through spring force or the pressure of the medium, ensuring straightforward and dependable control.
4. High Flow Capacity
Equipped with a pilot-operated configuration and an optimized fluid path, this series delivers excellent flow rates. Depending on the specific model, flow capacity ranges from 610 liters per minute up to 2600 liters per minute, accommodating a broad spectrum of medium to high flow demands.
5. Wide Operating Pressure Range
These valves typically operate within a pressure range of 0.2 MPa to 1.0 MPa (2 to 10 bar), with some versions supporting pressures up to 1.6 MPa (16 bar). It is crucial to maintain a minimum pressure differential—usually above 0.2 to 0.3 bar—for the pilot-operated valves to function correctly.
6. High-Quality Materials and Sealing
Constructed from die-cast aluminum alloy or aluminum extrusion, the valve bodies provide a lightweight yet sturdy and corrosion-resistant solution. The spool and sleeve can be configured with either metal seals for longevity or soft seals for enhanced flow. Sealing materials include NBR or FKM, compatible with compressed air and various other media.
7. Low Power Consumption and High Protection Rating
The solenoid coils feature remarkably low power usage, with some models consuming as little as 1 to 2 watts, delivering substantial energy savings. With an IP65 protection rating, the valves are safeguarded against dust ingress and water jets, making them well-suited for humid or dusty industrial environments.
8. Flexible Manual Override
Standard manual override options include push-buttons or twist-lock knobs. This feature allows for easy equipment commissioning, maintenance, and emergency manual operation without depending on electrical signals.
9. Diverse Ports and Mounting Options
The valve ports typically utilize British pipe thread standards such as G1/4, G3/8, or G1/2 for straightforward integration with various pneumatic systems. Mounting alternatives include inline piping or sub-base configurations, providing flexible installation options tailored to system-specific needs.
Applications:
Industrial Automation Production Lines
These valves are widely utilized in various automated assembly lines, material handling systems, and packaging machinery. Their primary role is to control single-acting cylinders, facilitating operations such as clamping, positioning, and pushing. Designed to meet the rigorous demands of high-frequency and high-reliability control, they ensure smooth and efficient production processes.
Single-Acting Actuator Control
A 3/2-way solenoid valve serves as the standard control element for single-acting pneumatic actuators, including single-acting cylinders, diaphragm valves, and pneumatic grippers. The normally open (NO) configuration is particularly advantageous in safety interlock scenarios, where the valve must automatically open or close during power outages. Such a feature is essential for emergency venting systems.
Purging and Pressure Relief Systems
In process industries that require periodic purging or pressure relief, these valves play a crucial role in managing the on/off flow of compressed air. They are extensively applied in filter blowback systems, surface dust removal devices, and safety relief circuits within air receiver tanks, contributing to the maintenance of equipment and workplace safety.
Packaging Machinery
Pneumatic actuators in packaging equipment such as filling machines, sealing machines, labeling machines, and blow molding machines rely on these valves for rapid and precise control. Their application ensures adherence to production cycle times and packaging accuracy, which are vital for maintaining product quality and efficiency.
Automotive Manufacturing and Parts Processing
In automotive production lines, these valves find applications in welding fixtures, painting setups, assembly stations, and parts processing machine tools. They control pneumatic tooling and auxiliary devices that demand oil resistance, vibration tolerance, and extended service life, supporting high-performance manufacturing environments.
Food and Beverage Production
Food processing equipment often incorporates these valves within pneumatic control systems for operations like blow molding, filling, and sealing. Selecting sealing materials and lubrication techniques that comply with food-grade standards is critical to maintain safety and hygiene throughout the production cycle.
Energy and Environmental Protection Equipment
These valves are integral components in environmental protection systems, including those used at thermal power plants, wastewater treatment facilities, and exhaust gas treatment stations. They control pneumatic valves for automated process management and enable remote operation, enhancing efficiency and environmental compliance.
Special Condition Applications
Certain models are engineered to function across wide temperature ranges, such as from –10°C to +50°C or beyond. In low-temperature settings, the use of dry air is recommended to prevent freezing. Additionally, for hazardous environments requiring explosion-proof measures, optional explosion-proof coils are available, complying with stringent safety standards.
