Model Number Breakdown
- V114A: SMC solenoid valve series code, V100 series
- 5: Rated voltage DC24V
- H: Lead wire configuration (direct lead-out, length 0.6m)
Working Principle
The V114A-5H employs a direct-acting solenoid valve structure. When the solenoid coil is energized, the generated electromagnetic force directly drives the valve spool, changing the state of the air passages to achieve directional control of compressed air. When de-energized, a spring force returns the spool to its original position.
Typical Application Scenarios
- Industrial Automation Production Lines Used in automated production lines such as automotive manufacturing and electronics assembly to control pneumatic actuators for tasks like workpiece pushing, positioning, clamping, and handling, improving production efficiency and product quality.
- Packaging Machinery Controls actions in packaging machines like material conveying, sorting, and marking, enabling rapid switching of pneumatic circuits to ensure precision and stability in the production process.
- Robotics Serves as part of the pneumatic control system in robots, controlling pneumatic actuators to perform tasks like workpiece grasping, positioning, and placement, enhancing robot motion precision and efficiency.
- Cleanroom Pneumatic Slides Provides precise pneumatic control for pneumatic slides in cleanroom environments such as semiconductor manufacturing and biopharmaceuticals, ensuring stable equipment operation in clean conditions.
Installation and Usage Precautions
- Installation Requirements The valve should be installed on a flat, stable base for stable operation. Before installation, check that the air supply pressure meets the 0.05~0.7 MPa requirement and ensure the air source is clean. Pay attention to the valve’s inlet/outlet direction during installation to ensure correct pneumatic connections.
- Operating Environment The operating temperature range is -10~50°C; avoid use in excessively high or low-temperature environments. Relative humidity should be kept below 90% to prevent moisture-related damage. The operating medium (air) should be filtered through a 40μm or finer filter.
- Regular Maintenance Periodically check the valve’s connecting pipes and electrical connections for leaks. Clean the valve surface regularly. Check the valve’s operational performance routinely to ensure long-term stable operation.
- Safe Operation Ensure proper equipment grounding before operation. Avoid contact with moving parts during operation. In case of equipment malfunction, stop immediately and consult qualified personnel. Always depressurize the system before installation to prevent injury.
Conclusion
The V114A-5H direct-acting 3-port solenoid valve is the “Precision Control Core” in the field of industrial automation. It perfectly combines large flow capacity, low power consumption, and fast response, providing an efficient, reliable, and convenient pneumatic control solution for various industrial applications.
