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.

I. Introduction to J-VALVES DBB Ball ValvesJ-VALVES DBB ball valves are high-performance industrial valves that are widely used in multiple industries such as petroleum, natural gas, chemical engineering, and electric power. Their unique Double Block and Bleed (DBB) function enables reliable sealing

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

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

J-VALVES always takes technological innovation as the core driving force for enterprise development, continuously increases investment in research and development, introduces advanced technologies and equipment, and cultivates a high-quality R & D team. The company has achieved a number of technolog

In the application of Trunnion ball valve, the DBB (Double Block and Bleed) seat design is a common choice. Its unique structure gives it significant advantages under specific working conditions. The following are the appropriate times to choose the DBB seat design and related considerations.Applica

DBB (Double Block and Bleed) ball valves and DIB (Double Isolation and Bleed) ball valves are two common types of industrial ball valves. They have significant differences in sealing principles, seat structures, and pressure relief mechanisms.

Application scenarios in petroleum refiningThe petroleum refining process involves high temperatures, high pressures and corrosive media, which places extremely high demands on the performance of valves. The DBB ball valve is suitable for a variety of media, including aviation kerosene, light oil, n

Technical Specifications of DBB BALL VALVESDouble block and bleed ball valve Body Material: Forging is selected. It has excellent mechanical properties, high strength and good toughness, can withstand high pressure, ensuring the reliability and stability of the valve body, preventing deformation and

The operational principle of the double block and bleed ball valve (DBB ball valve) unfolds as follows:When in the closed configuration, the ball snugly mates with the valve seat, thereby generating the initial sealing barricade. This barricade functions with great efficacy in impeding the onward pr

In the industrial field, BALL VALVES are widely used, and different standards have different requirements for their designs. API 6D and ASME B16.34 are two commonly used relevant standards. Understanding the differences in the design of DBB (DOUBLE BLOCK AND BLEED) BALL VALVES under these two standards is crucial for correct selection. The following will provide a detailed comparison and a selection guide.

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.
