In urban gas transmission and distribution systems, the correct selection of DBB ball valves is of vital importance as it is related to the safety and stability of gas transmission. Both the API 6D standard and the ISO 14313 standard play crucial roles in guiding the selection of ball valves. Understanding how they are applied synergistically can help us choose the most suitable DBB ball valves. Let's discuss it in detail below.
In industrial pipeline systems, DBB ball valves play a crucial role. When considering the life cycle cost of DBB ball valves, the two factors of installation simplification and extension of the maintenance cycle have a profound impact. Understanding the influencing factors involved in each of them helps enterprises make more economically beneficial decisions when selecting DBB ball valves. Now, let's conduct an in-depth analysis.
