Maintenance 

1. Pay attention to the storage environment of the valve. It should be stored in a dry and ventilated room, and both ends of the passage should be blocked.

2. The valve should be inspected regularly, and the dirt on it should be removed, and anti-rust oil should be applied to its surface.

3. The valve after installation and application should be checked and repaired regularly to ensure its normal operation.

4. Check whether the sealing surface of the valve is worn or not, and repair or replace it according to the situation.

5. The sealing performance of the valve should be tested to ensure its performance.
