2. Product Overview
"Boang Brand" single flange fully welded ball valve is specially customized by our factory according to the user's pipeline needs. The reason for the design of this product is that after other valves are installed in the pipeline, the fully welded ball valve cannot be directly installed. According to this situation, a single flange fully welded ball valve should be used. Single flange fully welded ball valve can be welded individually and the other end is connected by flange. The flange end can be connected to other valves or pipe flanges, and the other end is connected by welding to facilitate the replacement of valves at the flange end.

Five, installation precautions
The end welding of fully welded steel ball valves uses electric welding or manual welding. Overheating of the valve chamber should be avoided. The distance between welding ends cannot be too short to ensure that the heat generated during the welding process will not damage the sealing material. All valves should be opened during installation.
