3. Product Overview
"Boang Brand" Directly buried welded ball valves can be buried directly underground. There is no need to build high and large valve wells. Only small shallow wells need to be set up on the ground, which greatly saves construction costs and engineering. time. The length of the valve body and the height of the valve stem can be adjusted according to construction and design requirements. The processing accuracy of the sphere is very precise, the operation is light and there is no harmful interference. Since the valve seat is made of carbon fiber reinforced Teflon seals and butterfly springs, it has strong adaptability to pressure and temperature changes and will not cause any leakage within the marked pressure and temperature range.
4. Advantage products
Heating pipe networks are often buried underground. In order to control the valves, tall valve wells need to be built. Rain or snow water will wash garbage into the valve wells. These garbage wastes will be generated in the wells. A lot of harmful gases. Personal injury may occur when operators enter the valve well to operate the valve. Bursts in pipes and valves can also cause injuries to operators.
There are often debris in the heating pipe network due to construction, welding, corrosion and other reasons. When the medium flows, these debris will be carried to wash away the valve sealing structure, causing damage to the valve sealing surface and causing the valve to not close tightly. Turning off the valve becomes a decoration.
Ordinary valves and pipelines require flanges, screws, and gaskets to connect them. The connection between valves and pipelines wastes a lot of material resources and is not conducive to the global environment and energy conservation and emission reduction. For this reason, directly buried fully welded ball valves have been well developed.

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.
