2. Product Overview
"Boang Brand" flange directly buried relief ball valve is a gas ball valve with relief, including a ball valve body, and a pipe joint is connected to the switch joint of the ball valve body The long stem includes a long stem, which is covered with a protective tube. A relief unit device is provided in the pipeline controlled by the ball valve body. It includes a relief base that is connected with the pipe, and is placed on the relief base. The relief pipe is equipped with a relief valve at the upper end of the relief pipe, and the relief unit device and the long stem are fixed to each other through a bracket. It is practical, easy to use, easy to open and close, and is conducive to pipeline inspection.

Land and 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.
