How to Use a Butterfly Valve

A butterfly valve is a commonly used industrial control valve known for its simple structure, compact size, light weight, and ease of operation. Due to these advantages, it is widely applied across various industries. Below is a guide on how to use a butterfly valve:

1. Check the Valve Before Installation
   Before installation, inspect the butterfly valve for any external defects or internal contamination to ensure it is free from flaws and dirt.

2. Installation Process
   According to the design specifications of the pipeline, place the butterfly valve in the pipeline. Install the flanges on both ends of the valve and tighten the bolts securely.

3. Check the Operation
   After installation, attach the handle to the butterfly valve and rotate it to check if the valve operates smoothly and easily.

4. Opening and Closing the Valve
   When opening or closing the butterfly valve, rotate the handle slowly to prevent the butterfly disc from colliding with the sealing surface.

5. Ensure Correct Flow Direction
   When using the butterfly valve, always pay attention to the correct flow direction to prevent reverse operation, which could affect valve performance.

6. Regular Inspection and Maintenance
   During use, periodically check the valve’s sealing and operational status. It’s important to clean any debris or sediment from the pipeline and valve to maintain smooth operation.

7. Long-Term Storage
   If the butterfly valve is not in use for an extended period, close the valve and clean the interior to prevent rust and corrosion from developing.

In summary, attention to detail and following the proper operating procedures are essential for ensuring the butterfly valve’s normal operation and extending its service life.
