Double Block and Bleed (DBB) ball valves are critical components in fluid control systems, designed to provide reliable isolation and safety in various industrial applications. These valves are particularly important in high-pressure and high-temperature environments, such as oil and gas, chemical p
Selection Key Points(I) Working Pressure and TemperatureSelect appropriate pressure and temperature ratings according to the working conditions. The pressure ratings of DBB ball valves usually cover 150, 300, 600, etc., with a nominal pressure range of 16-100, and an applicable temperature range fro
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.
