Working Principle

The VX3114-01-5DZ1-B employs a direct-acting solenoid valve structure. When the solenoid coil is energized, it generates an electromagnetic force that directly drives the valve spool to move, changing the state of the air passage to achieve directional control of compressed air. When the solenoid is de-energized, a spring force returns the spool to its original position. The built-in magnet allows for valve spool position detection in conjunction with a magnetic switch, facilitating integration into automation control systems.

Typical Application Scenarios

1. Industrial Automation Production Lines Used in automated production lines such as automotive manufacturing and electronic equipment production to control the actions of pneumatic actuators, enabling workpiece pushing, positioning, clamping, and handling, thereby improving production efficiency and product quality.
2. Packaging Machinery Controls actions like material conveying, sorting, and marking in packaging machines. The solenoid valve enables rapid switching of pneumatic circuits, ensuring precision and stability in the production process.
3. Robotics Serves as part of the pneumatic control system in robots, controlling the actions of pneumatic actuators for tasks like workpiece gripping, positioning, and placement, enhancing the robot’s motion precision and efficiency.
4. Precision Manufacturing Equipment Used in semiconductor manufacturing and precision machining equipment to control the action accuracy of pneumatic actuators, ensuring process stability and repeatability, and improving product quality.

Installation and Usage Precautions

1. Installation Requirements The solenoid valve should be installed on a flat, stable base to ensure stable operation. Before installation, check that the air supply pressure meets the 0.05~0.7MPa requirement and ensure the air source is clean. During installation, pay attention to the inlet and outlet directions of the solenoid valve to ensure correct pneumatic connections.
2. Operating Environment The operating temperature range is -5~60°C; avoid use in high or low-temperature environments. Relative humidity should be kept below 90% to prevent moisture from affecting equipment lifespan. The operating medium should be filtered through a 40μm or finer filter before use.
3. Regular Maintenance Regularly inspect the solenoid valve’s connecting pipes and electrical connections to ensure no leaks. Periodically clean the surface of the solenoid valve to keep it clean. Routinely check the solenoid valve’s operational performance to ensure long-term stable operation.
4. Safe Operation Ensure the equipment is properly grounded before operation to prevent electric shock risks. Avoid contact with moving parts during operation to prevent injuries. In case of equipment malfunction, stop immediately and have it repaired by qualified personnel. Always depressurize the system before installation to prevent injury from high-pressure media discharge.
