Direct-buried fully welded ball valve

Overview:

The fully welded buried ball valve is a type of shut-off valve specially designed for underground pipeline systems. It achieves the opening or closing of the pipeline medium by the rotation of the ball around the valve stem. Unlike traditional flange-connected ball valves, its valve body adopts an integral welding process (without flange connection points) and can be directly buried in the underground soil without the need to build a ground valve well. Therefore, it has significant advantages in saving space, reducing engineering costs and enhancing the safety of the pipeline network.

Its core functional positioning is: to reliably cut off, regulate or isolate media (such as natural gas, hot water, crude oil, etc.) in underground pipe networks, while adapting to complex underground environments such as dampness, corrosion and temperature changes, ensuring long-term stable operation.

Nominal diameter: 10mm to 2000mm and 1/2" to 80".
