Working Principle
The VHK2A-06F-06F employs a poppet valve structure. Manual rotation of the knob drives the valve stem, moving the valve spool to change the state (open/closed) of the internal passage, thereby controlling the on/off function for compressed air. The knob position corresponds to the valve’s status, allowing operators to quickly identify the working state. The poppet valve design ensures excellent sealing performance, effectively preventing air leakage.
Typical Application Scenarios
- Industrial Automation Production Lines Used in automated production lines such as automotive manufacturing and electronics assembly for on/off control of pneumatic systems. It assists in 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 quick switching of pneumatic circuits to ensure precision and stability in the production process.
- 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.
- Laboratory Equipment Used in laboratory automation equipment for controlling pneumatic actuators, performing tasks like sample grasping, positioning, and placement, thereby improving experimental accuracy and efficiency.
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 requirements 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 0~60°C; avoid use in excessively high or low-temperature environments. Relative humidity should be kept within an appropriate range to prevent moisture-related damage. The operating medium (air) should be filtered before use.
- Regular Maintenance Periodically check the valve’s connecting pipes and the valve itself 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.
