How to correctly operate pneumatic butterfly valves with manual operation

To correctly operate a manually operated pneumatic butterfly valve and avoid damage or accidents caused by excessive force or improper operation, the following steps can be followed:

1. Confirm the operating device: Firstly, confirm the position and type of the manual operating device, understand its working principle and usage method.

2. Cut off power: Before performing any operation, be sure to cut off the power to ensure safety.

3. Adjust position: Adjust the manual operating device to the desired position as needed to ensure smooth operation.

4. Light force operation: Use appropriate force to operate and avoid excessive force. Generally speaking, when manually opening a butterfly valve, the force should not exceed 15 kilograms. If you feel it is difficult, you should first troubleshoot before proceeding with the operation.

5. Reverse handle: After the butterfly valve is closed, the handle should be reversed one or two turns to facilitate the reopening of the butterfly valve.

6. Remove sediment: There may be sediment deposition areas near the butterfly valve that is closed for a long time, which can create resistance to the opening and closing of the butterfly valve. When opening, the opening and closing actions should be repeated to promote the loosening of sediment.

7. Pay attention to observation: During the operation, pay attention to the opening and closing of the butterfly valve to ensure its normal operation.

8. Regular maintenance: Regularly maintain the manual operating device and butterfly valve, such as cleaning, lubrication, fastener inspection, etc., to ensure their normal operation.

9. Pay attention to safety: During the operation, pay attention to safety, comply with relevant operating norms and safety operation requirements, and avoid accidents.
