Common faults and troubleshooting of pneumatic plastic diaphragm valves

1. Before installation, confirm that the performance of our product and the flow direction arrow of the medium are consistent with the operating conditions, and insert them into the valve cavity for cleaning. The front panel is allowed to have no foreign objects in the seal and butterfly, and the disc must not be closed without washing to avoid damaging the sealing ring.

2. In the pipeline, the installation position of the vertical device is *, but it is not flipped over.

3. During use, it is necessary to adjust the flow rate, which is controlled by a worm gear box.

4. Open and close the disc valve by a factor of more than two months, and the worm opens the cover to check if the appropriate amount of butter should be maintained.

5. The urgent requirement for inspection is to ensure the filling of bees and the flexible connection of the valve stem rotation.

6. Metal sealed butterfly valve products are not suitable for installation at pipeline terminals. If they must be installed at pipeline terminals and equipped with outlet flanges, measures can be taken to prevent ring buildup and excessive distance.

7. Regularly check the function of the valve in response to dry installation, and promptly troubleshoot any faults found.
