Discover the J-VALVES DN50 PN16 three-piece trunnion ball valve with DBB function. Learn how double block and bleed improves safety, sealing, and maintenance efficiency.
As a type of industrial valve with high performance and reliability, fully welded ball valves are widely used in the petroleum, natural gas, chemical, metallurgical, electric power and other industries. It is crucial to ensure the reliability of their performance before installation and commissionin
Structure and Principle of Fully Welded Ball ValvesThe valve body is welded from steel pipes into an integral sealed structure. The ball is connected to the driving device through the valve stem, and the opening and closing can be realized by rotating the ball. When opened, the through hole of the b
Recently, an exciting news came from our J-VALVES team. That is, the fully welded ball valve has been successfully exported to Russia and delivered smoothly! Behind this achievement, countless efforts and hard work of the team are condensed. From the careful research and development of products,
Understanding ANSI B16.34What is ANSI B16.34?ANSI B16.34 is a widely recognized standard developed by the American Society of Mechanical Engineers (ASME) and the American National Standards Institute (ANSI). It specifies the requirements for the design, construction, testing, and marking of valves,
API 6D: Pipeline Valves StandardOverviewAPI 6D, titled "Specification for Pipeline and Pipeline-Related Valves," is specifically designed for valves used in petroleum and natural gas pipeline systems. It provides detailed requirements for the design, construction, testing, and marking of pipeline va
Overview of Common Materials for Full-Welded Ball ValvesThe material selection for full-welded ball valves is diverse, mainly including carbon steel, stainless steel, alloy steel, cast iron, and copper alloys. Each material has its unique physical and chemical properties, making it suitable for diff
Understanding Full-Welded Ball ValvesKey Features• Welded Construction: Full-welded ball valves feature a seamless construction, ensuring a robust and leak-tight design.• Durability: These valves are designed to withstand high pressures and harsh operating conditions, making them suitable for demand
Full-welded ball valves are essential components in fluid control systems, widely used across various industries for their durability, reliability, and ability to provide precise flow control. When it comes to selecting the right material for full-welded ball valves, understanding the performance di
Understanding Ball Valve DesignsFull-Bore Ball ValvesFull-bore ball valves, also known as full-port or full-diameter ball valves, have an internal diameter that matches the diameter of the connecting pipeline. This design ensures that the fluid flow is not restricted when the valve is open, providin
Flanged End Ball ValvesDesign and Operation• Flange Design: Flanged end ball valves feature flanges at both ends, allowing for easy installation and removal without the need to cut or weld pipes. This design ensures a secure connection and minimizes the risk of leaks.• Operation: The ball valve oper
