The DBB Function of Pipeline Ball Valves

Pipeline ball valves are essential components widely used in oil, gas, and other industrial pipeline systems. One of the most important features of these valves is their DBB (Double Block and Bleed) function, which plays a critical role in ensuring pipeline safety. The DBB function helps vent or drain the medium inside the ball valve body. This prevents pressure buildup and stops harmful substances from leaking out, improving the overall safety and stability of the system. In this article, we'll...
