2. Overview of products
"Boang Brand" gear transmission flange long stem fully welded ball valve can be directly buried underground. There is no need to build a high and large valve well. Instead, only a small shallow well is set up on the ground, which greatly saves money. Construction cost and project time. The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline. The processing accuracy of the sphere is very precise, the operation is light and there is no harmful interference. The use of high-grade raw materials can protect the above pressure. Compared with products of the same specification in similar industries, the valve body is small and beautiful in appearance. And it can prevent the risk of gas explosion. The fully welded ball valve is a very safe valve. When the directly buried ball valve is driven, the operator does not need to go underground and only needs to perform the transmission operation on the ground, which is very safe and convenient.
3. Product usage

4. Performance characteristics
The valve body structure is integrally welded and there will be no external leakage
The valve seat is composed of a sealing ring and a spring and has strong adaptability to changes in pressure and temperature. There will be no leakage within the scope of use. The anti-leakage structure of the valve stem has a self-sealing gasket and a shaped sealing ring at the bottom of the valve stem. There is a shaped sealing ring on the top. The two sealing gaskets ensure that no leakage occurs. Leakage
The valve body material is the same as the pipe material, so there will be no uneven stress, nor will it be extruded and deformed due to earthquakes and vehicles passing over the ground.
The valve body is light and easy to keep warm.

Land, installation notes
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.
