四、Operation Instruction
- Press reset type: Press the valve handle to sample. Release the handle after sampling, and the valve will reset automatically.
- Handwheel type: Rotate the handwheel to open and close the valve. Rotate reversely to close the valve after sampling.
- Handwheel reset: Return the valve to its initial position after sampling.
五、Maintenance
- Check the sealing performance regularly to avoid leakage.
- For corrosive media, inspect the integrity of lining materials periodically and replace components when necessary.
- Keep the valve clean to prevent impurities from affecting sampling accuracy.
六、Safety Notes
- Ensure pipeline pressure drops to a safe range before operation.
- Wear proper protective equipment during sampling and avoid direct contact with harmful media.
- Inspect valve functions regularly to guarantee normal operation.
