Can butterfly valves be installed upside down? The answer is no.

The reason is very simple, the butterfly valve can play a sealing role with the seat sealing ring and the valve shaft part of the packing. When the butterfly valve is installed vertically or horizontally, the medium has little erosion on the packing part. When the butterfly valve is installed upside down, the medium will flow into the packing and erode the packing, destroying the sealing performance and causing the leakage of the butterfly valve. If it is the leakage of toxic and harmful media, it will cause great security risks.

# Installation points:

1. Pre-cleaning: the valve body and pipeline should be thoroughly cleaned, and the butterfly plate should be kept open before installation

2. Flange requirements: clamping butterfly valves must be equipped with special flanges

3. Fastening standard: the connection part should be pressed tightly to the best packing seal and the valve stem rotation is flexible

4. Operation and maintenance requirements: check the sealing performance regularly

Installation quality and valve quality jointly determine the operation effect, so the purchase of high-quality butterfly valve products is also the key. www.carbonvalve.com provides industrial butterfly valve solutions
