Product Overview
Directly buried welded ball valves can be directly buried underground without the need to build large valve chambers. Only small shallow pits need to be set on the ground, greatly saving construction costs and engineering time. The length of the valve body and the height of the stem can be adjusted according to pipeline construction and design requirements. The ball has extremely high machining precision, ensuring easy operation without adverse interference. High-grade raw materials are used to ensure pressure ratings above PN25. Compared with similar products of the same specifications in the industry, the valve body is smaller and has an attractive appearance. Moreover, it can prevent the danger of gas explosions; fully welded ball valves are extremely safe valves. When operating the directly buried ball valve, the operator does not need to enter the underground; they only need to perform the transmission operation above ground, which is very safe and convenient.
