3. Transportation Precautions

Proper handling and transportation are essential to prevent damage during delivery.

Key Considerations:

• Protective Packaging: Each valve should be packed with shock-absorbing material to protect the fluorine lining and disc.

• Moisture Protection: Store and transport in dry environments; avoid exposure to rain or humidity.

• Upright Positioning: Valves should be kept in an upright position to prevent stress on the stem and sealing seat.

• Avoid Heavy Pressure: Do not stack heavy loads on the valve body to avoid deformation.

• Transport Temperature Control: Extreme heat or cold may damage the fluorine lining; maintain stable conditions.
