Understanding Double Block-and-Bleed (DBB) Ball ValvesDBB ball valves are designed to provide two independent seals (one upstream and one downstream) and a bleed port to vent any trapped fluid between the seals. This design ensures that the valve can safely isolate a section of the pipeline and reli

The Double Ball Floating Ball Valve is an advanced fluid control device, specially suitable for high-pressure, high-temperature and low-temperature environments in industries such as petroleum, natural gas and chemical engineering. With its unique double isolation design and excellent sealing perfor

Over the past decade, industrial-grade stainless steel DBB (Double Block & Bleed) ball valves have gradually evolved from a "high-end optional component" to an indispensable key safety element in systems such as oil and gas, chemical engineering, refining, offshore engineering, hydrogen energy, and high-purity medium transportation. As global factories continue to raise requirements for safety levels, emission standards, and automation capabilities, DBB ball valves are accelerating the replacement of traditional dual-valve structures and have become one of the product categories with the greatest growth potential in future industrial fluid systems.

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 high-pressure pipeline systems, DBB ball valves are widely used, and their anti-blowout valve stem and self-relieving structures play a crucial role in ensuring the overall safety performance. The following will analyze in detail how these two structures enhance the safety performance of DBB ball valves in high-pressure pipelines.

DOUBLE BLOCK AND BLEED (DBB) BALL VALVES are widely used in numerous industrial fields, and the fireproof and anti-static designs are crucial for their operational safety. Under the API 6FA standard, there are comprehensive safety redundancy mechanisms to ensure the reliable operation of BALL VALVES under special working conditions. The following will introduce the relevant content in detail.

Design Standards for DBB Ball ValvesAPI 6DAPI 6D is a widely recognized standard for pipeline valves, particularly those used in the oil and gas industry. It covers various types of valves, including ball valves, and provides detailed requirements for design, materials, testing, and marking. Key asp

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

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.
