A large - scale petroleum company in Malaysia, for one of its important petroleum refining, transportation, and storage projects, faced strict valve equipment selection. The project covers multiple links from crude oil reception, refining to petroleum product storage and long - distance transportation, and has extremely high requirements for the performance, reliability, and safety of valves.

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 r

In oil and gas pipelines, DBB ball valves are like "gatekeepers" controlling the flow of media. Especially within the wide pressure range from 150LB to 2500LB, whether they can stably withstand pressure and comply with international standards is directly related to the safety of the pipelines. Today, let's talk about how to conduct a comprehensive "check-up" for ball valves through pressure resistance testing and verification against the ASME B16.34 standard.

Recently, J-VALVES received good news. The DBB ball valves (Double Block and Bleed Ball Valves) supplied for a key project have successfully passed the customer's acceptance. During this acceptance, the customer formed a professional team to conduct a comprehensive and strict inspection of the produ
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
DBB ball valves play a crucial role in industrial pipeline systems. With its unique double block and bleed design, it can ensure that when the valve is closed, the medium in the pipeline is effectively blocked, and at the same time, the residual medium in the valve chamber can be discharged, greatly
