Can the butterfly valve be installed upside down?

When the butterfly valve is installed vertically upward or horizontally, the medium will erode the packing part.

Although the demand for butterfly valves is increasing now, in more and more working conditions, butterfly valves have become people's first choice. However, there are still many friends who do not understand the installation of butterfly valves, or do not understand them thoroughly enough. In this article, the editor of Bundor Valve will share with you the installation of butterfly valves, and answer the question "Can butterfly valves be installed upside down", hoping to learn and grow together with you.

Can the butterfly valve be installed upside down? The answer is no. The reason is very simple, the sealing function of the butterfly valve is the seat sealing ring and the packing of the valve shaft part. When the butterfly valve is installed vertically upward or horizontally, the medium will erode the packing part. When the butterfly valve is installed upside down, the medium will flow to the packing to erode the packing, destroy the sealing performance, and cause the leakage of the butterfly valve. It is the leakage of toxic and harmful media, which will cause great safety hazards.

In addition to not being flipped, there are a few things to note about butterfly valve installation:

1 Before installation, clean the inside of the butterfly valve body and the inside of the pipeline to ensure that the medium flow space is clean and free of impurities. The butterfly disc cannot be closed until it is cleaned.

2 Wafer butterfly valves should use special flanges for wafer butterfly valves during installation.

3 Each connection part of the butterfly valve should be pressed tightly to ensure that the packing part obtains the maximum sealing performance, but it cannot affect the rotation of the valve stem.

4 After the butterfly valve is installed, it should be checked regularly during operation, and problems should be dealt with in time.

The quality of the butterfly valve installation is one of the two key factors that affect the operation of the butterfly valve. Another thing that affects the operation of the butterfly valve is the quality of the butterfly valve, so it is also the key to purchase high-quality butterfly valve products. Bundor Valve, a manufacturer of high-quality butterfly valves, welcome to inquire.
