working principleBall ValveThe core component of a ball valve is a sphere with a central hole. The fluid is cut off and opened by rotating the sphere 90 degrees. The sphere is installed in the valve body and closely cooperates with the valve seat to form a seal. When the hole of the sphere is aligne

I. Overview of J-VALVES Small Bore Metal Sealed Gate ValvesJ-VALVES SMALL BORE METAL SEALED GATE VALVES are a type of valve product specifically designed for high-demand working conditions. Their core feature is the adoption of a metal-to-metal sealing method, which enables them to maintain excellen

Understanding J-VALVES' High-Performance Gate ValvesJ-VALVES' high-performance gate valves are designed with advanced engineering principles to ensure they can withstand the rigors of industrial use. These valves are available in a variety of sizes, materials, and configurations, allowing them to be

ISO 14726 Standard OverviewISO 14726 is an international standard that specifies the requirements for the design, manufacturing, and testing of valves, particularly for corrosive environments. It covers various types of valves, including ball valves and gate valves, and provides detailed guidelines

ISO 13628-4 Ball ValvesStandard OverviewISO 13628-4 is part of the ISO 13628 series, which specifies requirements for subsea production systems. This particular standard focuses on the design, manufacturing, and testing of subsea equipment, including ball valves. It is widely used in the oil and gas

DIN 3352 Ball ValvesDesign and Sealing Mechanism• Floating Ball Design: DIN 3352 ball valves typically feature a floating ball design, where the ball is not rigidly fixed to the stem. This allows the ball to move slightly under pressure, ensuring a tight seal against the seat.• Bidirectional Sealing

Feature/Aspect API 600 ASME B16.34 **Construction** Heavy-duty steel, full-port design Standard steel, available in various materials **Sealing** Enhanced with backseat, lantern ring Standard sealing, suitable for general applications **Maintenance** Easy access, bolted bonnet

In industrial piping systems, the selection of valves is crucial for the safe operation, efficiency and reliability of the system. Gate valves and ball valves are two common types of valves, each having its own advantages and disadvantages in terms of structure, performance and application scenarios

In the industrial field, J-VALVES red flange gate valves have become an ideal choice in numerous scenarios with their unique charm. Inside industrial plants, the pipelines in industries such as chemical and petroleum are crisscrossed, just like a complex network. The red flange gate valves stand out conspicuously in this "steel jungle". When workers conduct inspections and operations, they can quickly locate these valves due to their eye-catching red color and efficiently control the cut-off or conduction of fluids, ensuring that the production process proceeds in an orderly manner. The professionalism they convey also meets the strict requirements of high-quality valves in industrial production.

Understanding ISO Standards for Gate ValvesWhat is ISO?The International Organization for Standardization (ISO) develops and publishes a wide range of international standards that ensure products and services are safe, reliable, and of high quality. For gate valves, ISO standards cover design, manuf

Understanding Soft Seated Gate ValvesDesign and ConstructionSoft seated gate valves consist of several key components, each contributing to their overall functionality and performance. The main components of a soft seated gate valve include:Body: The body of the valve serves as the main housing and

Butterfly Valves in the Chemical IndustryDesign and Performance• Compact Structure: Butterfly valves are known for their compact design, which makes them suitable for applications with limited space. They consist of a circular disc that rotates around a central axis to control fluid flow.• Low Flow

Understanding Gate Valve DesignsBidirectional Sealing Gate ValvesBidirectional sealing gate valves are designed to provide tight sealing in both directions of fluid flow. This means they can effectively prevent backflow and maintain pressure integrity regardless of the flow direction. These valves t

Manual OperationGate Valves• Design and Operation: Manual gate valves typically feature a handwheel that is connected to a threaded stem. Turning the handwheel causes the stem to move linearly, raising or lowering the gate to open or close the valve.Advantages• Ease of Use: Manual operation is strai

Gate Valves: Water Supply SystemsDesign and Operation• Structure: Gate valves feature a sliding gate that moves vertically to control fluid flow. When fully open, the gate is completely out of the flow path, allowing for unrestricted flow.• Operation: Gate valves are designed for on-off control, pro
