The process of assembly procedure for double flanged butterfly Valve

This video shows, the assembly procedure for a double flanged butterfly valve involves a series of precise steps to ensure proper functionality and sealing performance. The process begins with inspecting all components—body, disc, shaft, seat, and seals—for cleanliness and quality.

First, the valve seat is positioned inside the valve body, followed by the insertion of the disc, which must be aligned carefully within the seat. The shaft is then inserted through the disc and body, securing the disc’s rotation axis.

Next, bearings, bushings, and seals are installed to ensure smooth operation and leak prevention. The valve is then bolted between two pipe flanges, and a handle or actuator is attached to control the disc’s movement.

Finally, the assembled valve undergoes pressure testing to verify tight sealing and correct operation before being approved for use in pipelines.
