Overview:A flange valve is a type of valve commonly used in industrial piping systems. Its main feature is that it is secured to the pipeline using a flange connection. Flange valves are widely used in fields such as oil, natural gas, chemical, and power industries, and they are suitable for pipelines that transport media such as water, oil, and gas. Below is a detailed introduction to flange valves:

Overview:A flange valve is a type of valve commonly used in industrial piping systems. Its main feature is that it is secured to the pipeline using a flange connection. Flange valves are widely used in fields such as oil, natural gas, chemical, and power industries, and they are suitable for pipelines that transport media such as water, oil, and gas. Below is a detailed introduction to flange valves: Types of Flange Valves 1. Flanged Ball Valve: -Features: The ball serves as the closing element, which opens or closes the pipeline by rotating 90 degrees. -Applications: Suitable for situations requiring quick opening and closing with good sealing performance, widely used in the oil, natural gas, and chemical industries. 2. Flanged Butterfly Valve:  -Features: The disc serves as the closing element, which adjusts the flow by rotating 90 degrees.  -Applications: Suitable for large diameter pipeline systems, commonly found in water treatment, environmental protection, and light industries. 3. Flanged Globe Valve: -Features: The valve is opened or closed by rotating the handwheel to drive the valve stem, causing the disc to move vertically.  -Applications: Suitable for situations requiring frequent operation and high sealing performance. 4. Flanged Gate Valve: -Features: The gate serves as the closing element, which controls the fluid passage by moving the gate up and down through handwheel rotation. -Applications: Suitable for fully open or fully closed pipeline systems, widely used in water, construction, and chemical industries. 5. Flanged Check Valve:  -Features: Prevents backflow of the medium, with the disc automatically opening and closing based on the flow of the medium and its own weight. -Applications: Commonly used at pump outlets and storage tank systems to prevent backflow that could damage equipment or the system. Main Advantages of Flange Valves 1. Good Sealing Performance: Flange connections offer better sealing performance than threaded connections, effectively preventing leaks. 2. High Strength: Flange connections can withstand higher pressures and temperatures, suitable for high-pressure, high-temperature pipeline systems. 3. Easy Installation and Maintenance: Flange valves are easy to install and disassemble, making it convenient to maintain and replace the valves. 4. Wide Applicability: Flange valves can be used for various media and working conditions, offering broad applicability. Application Fields of Flange Valves - Oil and Natural Gas Industry: Used for the transportation and regulation of crude oil, natural gas, and other media in pipeline systems. - Chemical Industry: Suitable for the transportation and control of various corrosive media. - Power Industry: Used in power plants for the transportation and control of steam, water, and other media. - Water Treatment Systems: Used for fluid control in various water treatment processes. Factors to Consider When Choosing Flange Valves 1. Working Pressure and Temperature: Select the appropriate flange valve based on the working pressure and temperature of the pipeline system. 2. Media Characteristics: Consider the corrosiveness, viscosity, and other characteristics of the medium to choose the appropriate valve material. 3. Pipeline Specifications: Select the corresponding flange standard and size based on the pipeline diameter and connection method. 4. Operation Method: Choose the suitable operation method, such as manual, electric, or pneumatic. Conclusion:As important components in industrial piping systems, flange valves offer good sealing performance and strength, making them suitable for various complex working environments. Their diverse types and wide application fields make flange valves significant in industrial production. Selecting the appropriate flange valve is crucial to ensuring the safe and reliable operation of the system. Disclaimer
