Product Description:
Product Features
1. Pilot-Operated Design
This solenoid valve series employs a pilot-operated principle, where the pilot valve governs the main spool’s movement. The pilot valve is actuated by the solenoid coil, while the main spool moves due to the pressure difference of the medium. Such a design enables a low-power solenoid coil to control high flow rates efficiently, making it ideal for applications with elevated pressure requirements.
2. Normally Open (NO) Function
The valves are set to be normally open by default, meaning they allow flow when de-energized. Energizing the solenoid coil closes the valve, stopping the medium flow. This feature is particularly beneficial for safety-critical systems where maintaining flow during power loss is essential, such as in cooling or emergency venting setups.
3. Single Solenoid Operation
Operating via a single solenoid coil, the valve transitions between open and closed positions by energizing or de-energizing the coil. When de-energized, the valve returns to its normally open state automatically through either spring force or medium pressure, ensuring straightforward and dependable control.
4. High Flow Capacity
The combination of the pilot-operated mechanism and optimized internal flow paths provides outstanding flow capacity. Depending on the specific model, flow rates range from 610 L/min up to 2600 L/min, accommodating a wide spectrum of medium to high flow demands.
5. Wide Operating Pressure Range
These valves operate effectively within a pressure range of 0.2 MPa to 1.0 MPa (2 to 10 bar), with certain versions capable of handling pressures as high as 1.6 MPa (16 bar). It is noteworthy that a minimal pressure differential, generally above 0.2 to 0.3 bar, is necessary for proper valve operation.
6. High-Quality Materials and Sealing
The valve bodies are crafted from die-cast aluminum alloy or aluminum extrusion, providing a lightweight yet robust and corrosion-resistant structure. Options for the spool and sleeve include metal-sealed types for extended durability or soft-sealed types optimized for higher flow. Sealing materials such as NBR or FKM are used, suitable for compressed air and diverse media.
7. Low Power Consumption and High Protection Rating
Featuring solenoid coils with low power usage, some models operate on as little as 1 to 2 watts, contributing to energy savings. The valves generally hold an IP65 protection rating, ensuring they are dust-tight and protected against water jets, making them well-suited to harsh industrial environments.
8. Flexible Manual Override
A manual override mechanism is standard, typically provided as either a push-button or a twist-lock knob. This feature facilitates easy commissioning, maintenance, and emergency manual operation without dependence on electrical signals.
9. Diverse Ports and Mounting Options
The valves come with port threads commonly sized at G1/4, G3/8, or G1/2 British standard pipe threads, adhering to international norms for seamless integration with pneumatic components. They also support both inline piping and sub-base mounting, offering flexible installation choices tailored to system needs.
Applications:
Industrial Automation Production Lines
These automation components are extensively utilized across various automated assembly lines, material handling systems, and packaging machines. They are designed to control single-acting cylinders used for tasks such as clamping, positioning, and pushing. Their operation supports high-frequency switching and offers reliable control to meet demanding industrial requirements.
Control of Single-Acting Actuators
The 3/2-way solenoid valve is a common solution for managing single-acting pneumatic actuators, including single-acting cylinders, diaphragm valves, and pneumatic grippers. Valves with a normally open (NO) configuration are especially ideal for safety interlock scenarios, where the valve must automatically open or close if power is lost. This makes them suitable for critical applications like emergency venting systems.
Purging and Pressure Relief Applications
In processes requiring periodic air purging or pressure relief, these valves regulate the on/off control of compressed air. They play an essential role in systems such as filter blowback mechanisms, devices for surface dust removal, and safety relief circuits for air receiver tanks, ensuring smooth and safe operation.
Usage in Packaging Machinery
These valves are widely implemented in a variety of packaging equipment, including filling machines, sealing machines, labeling devices, and blow molding machines. They control the rapid movements of pneumatic actuators, helping to maintain efficient production cycle times and precise packaging standards.
Automotive Manufacturing and Parts Processing
On automotive production lines, they are used in welding fixtures, painting equipment, assembly stations, and parts processing tools. The valves control pneumatic tooling and auxiliary apparatuses, requiring resistance to oil, vibration resilience, and a long service lifespan to withstand the harsh conditions of automotive manufacturing environments.
Applications in Food and Beverage Production
These pneumatic control components are suitable for use in food processing machinery, including blow molding, filling, and sealing operations. By selecting sealing materials and lubrication methods that comply with food-grade standards, they ensure product safety and maintain hygiene throughout the manufacturing process.
Energy and Environmental Protection Equipment
In the field of environmental protection, these valves are deployed in systems like thermal power plants, wastewater treatment facilities, and exhaust gas processing plants. They operate pneumatic control valves and on/off valves to facilitate automated process control and enable remote operation, helping to protect the environment effectively.
Special Condition Implementations
Certain valve models are designed for use under special conditions, such as wide temperature ranges from –10°C to +50°C or beyond. In colder environments, dry air supply is recommended to avoid freezing. For hazardous locations requiring explosion-proof measures, optional explosion-proof coils are available to meet the necessary safety standards.
