The efficient performance of BCST butterfly valves can significantly improve the productivity of an organization. Its fast response and precise adjustment make the fluid flow in the pipeline smoother, reducing the risk of energy waste and production interruption. At the same time, the butterfly valve’s high-quality sealing performance effectively prevents fluid leakage, ensuring the safety and stability of the production environment.

Butterfly valves, as crucial fluid control devices, may encounter some common issues during practical use. Here are some of the frequently encountered problems and their corresponding solutions:

1. Seal Face Leakage

Problem Cause:

1.Debris trapped between the disc and the seal ring.
2.Uneven or insufficient tightening of the flange bolts on the outlet side.
3.Incorrect pressure testing direction.

Solution:

1.Clean the interior of the valve to eliminate debris, ensuring that the disc and seal ring are free from impurities.
2.Inspect and adjust the tightening force of the flange bolts to ensure uniform compression.
3.Conduct pressure testing in accordance with the specified direction to ensure effective sealing.

2. Leakage from Both Ends of the Valve

Problem Cause:

1.Failure of the sealing gaskets on both sides.
2.Uneven or insufficient tightening of the pipe flange.

Solution:

1.Replace the failed sealing gaskets, ensuring that the gaskets meet quality requirements.
2.Check and adjust the tightening force of the pipe flange to ensure uniform and sufficient compression.

3. Insensitive Operation

Problem Cause:

1.Stuck sealing face.
2.Faulty transmission device.

Solution:

1.Inspect and clean the sealing face to eliminate sticking issues.
2.Inspect the transmission device to ensure it functions properly, and repair or replace it promptly if any faults are found.

4. Loud Noise

Problem Cause:

Excessively high fluid velocity or unstable operation.

Solution:

1.Reduce fluid velocity by adjusting the valve size or installing flow restrictors.
2.Inspect and adjust the transmission device to ensure stable valve operation.

5. Leakage Current

Problem Cause:

1.Conductive substances present in the leaking liquid.
2.Electrical grounding issues.

Solution:

1.Clean the leaking liquid to avoid contamination by conductive substances.
2.Inspect the electrical grounding system to ensure proper grounding, and promptly repair any faults.
Additionally, to ensure the smooth operation and extended lifespan of butterfly valves, it is crucial to follow these guidelines:

1.Before installation, confirm that the product performance and flow direction arrow align with the operating conditions to avoid incorrect installation.
2.Regularly inspect the tightness of all connection parts to maintain sealing performance and the smooth rotation of the valve stem.
3.For butterfly valves with frequent opening and closing, regularly inspect and replace the lubricating grease to ensure the smooth operation of the worm gearbox.

By following proper installation procedures, correct usage, and timely maintenance, common issues encountered during the use of butterfly valves can be effectively avoided and resolved, ensuring stable operation and long-term durability.
