Product Description:
Product Features
1. Pilot-Operated Design
This series of solenoid valves utilizes a pilot-operated mechanism, where the pilot valve governs the movement of the main spool. The solenoid coil drives the pilot valve, while the main spool responds to the pressure differential of the medium. Such a design enables a low-power solenoid coil to manage the on/off function for large flow rates, improving energy efficiency and suitability for higher pressure environments.
2. Normally Open (NO) Function
The valve’s default status is normally open, allowing the medium to flow when it is de-energized. When the solenoid coil is energized, the valve shuts off the flow by closing. This normally open feature is ideal for safety-critical applications where continuous medium flow is required during power outages, such as cooling systems or emergency venting operations.
3. Single Solenoid Operation
Employing a single solenoid control, the valve transitions between open and closed states by energizing or de-energizing the solenoid coil. Once the coil is de-energized, the valve automatically reverts to the normally open position through spring force or medium pressure, ensuring straightforward and dependable control.
4. High Flow Capacity
Owing to its pilot-operated design and optimized flow path, these solenoid valves deliver excellent flow capacity. Flow rates vary by model, ranging from 610 liters per minute up to 2600 liters per minute, accommodating a broad array of medium to large flow scenarios.
5. Wide Operating Pressure Range
The valves operate within a pressure range typically spanning 0.2 MPa to 1.0 MPa (2 to 10 bar), with some variants capable of handling pressures as high as 1.6 MPa (16 bar). It is important to note that pilot-operated valves require a minimum pressure differential, generally around 0.2 to 0.3 bar, to function correctly.
6. High-Quality Materials and Sealing
Constructed from die-cast aluminum alloy or aluminum extrusion, the valve body is lightweight yet robust and corrosion-resistant. The spool and sleeve come in two sealing options: metal-sealed for long lifespan or soft-sealed for high flow. Sealing materials include NBR or FKM, making the valve suitable for compressed air and various other media.
7. Low Power Consumption and High Protection Rating
The solenoid coil is designed for low energy use, with certain models drawing as little as 1 to 2 watts, ensuring energy savings. The valves typically have an IP65 protection rating, meaning they are dust-tight and can resist water jets, making them appropriate for damp and dusty industrial environments.
8. Flexible Manual Override
Each valve includes a manual override feature available as a push-button or twist-lock knob. This functionality assists with equipment setup, maintenance, and emergency manual control without dependence on electrical signals.
9. Diverse Ports and Mounting Options
The valves come with port threads such as G1/4, G3/8, or G1/2 British pipe thread standards, facilitating easy integration with various pneumatic components worldwide. Installation flexibility is also provided through support for both inline piping and sub-base mounting configurations, catering to varied system integration needs.
Applications:
Industrial Automation Production Lines
Industrial automation production lines employ automated assembly processes, material handling systems, and packaging machines to manage single-acting cylinders. These systems handle tasks such as clamping, positioning, and pushing, meeting the stringent requirements for high-frequency operation and reliable control performance.
Control of Single-Acting Actuators
The 3/2-way solenoid valve is a fundamental component used to operate single-acting pneumatic actuators, including single-acting cylinders, diaphragm valves, and pneumatic grippers. Valves designed with a normally open (NO) configuration are especially advantageous in safety interlock systems, where automatic valve operation is critical during power failures, such as in emergency venting scenarios.
Applications in Purging and Pressure Relief
This type of valve is also integral to process systems that require regular purging or pressure relief. It controls the start and stop of compressed air flow in applications like filter blowback mechanisms, surface dust extraction devices, and safety relief circuits linked to air receiver tanks.
Use in Packaging Machinery
Packaging equipment such as filling machines, sealing units, labeling devices, and blow molding machines rely heavily on these valves to manage the fast operation of pneumatic actuators. This ensures efficient production cycles and precise packaging outcomes.
Role in Automotive Manufacturing and Parts Processing
Within automotive production lines, these valves control pneumatic tools and auxiliary equipment used in welding fixtures, painting systems, assembly stations, and component processing machinery. The equipment is designed to withstand oil exposure, vibrations, and maintain a long operational lifespan.
Food and Beverage Industry Applications
In food and beverage manufacturing, pneumatic control systems incorporate these valves for processes like blow molding, filling, and sealing. The selection of sealing materials and lubricants complies with food-grade standards, ensuring hygienic and safe production environments.
Energy and Environmental Protection Equipment
These valves are frequently utilized in environmental protection systems, including thermal power plants, wastewater treatment facilities, and exhaust gas purification equipment. They operate pneumatic control valves to facilitate automated process management and support remote operation capabilities.
Special Conditions and Safety Features
Certain valve models are engineered to function across wide temperature ranges, such as from –10°C to +50°C or beyond. In cold environments, the use of dry air helps prevent freezing. Additionally, for hazardous locations requiring explosion-proof measures, optional explosion-proof coils are available to ensure compliance with safety regulations.
