WKT's double-eccentric flanged butterfly valve is a high-performance butterfly valve, that is widely used in water plants, power plants, steel mills, the chemical industry, water source spring projects, environmental facilities construction, and other system drainage, especially suitable for waterway pipelines, as a regulating and intercepting device.
This butterfly valve is famous for its unique double-eccentric design, one of which is the eccentricity of the valve stem axis deviation from the center of the butterfly plate, and the other eccentricity is the valve stem axis deviation from the center line of the pipeline. This design allows the butterfly plate to quickly detach from the valve seat when opening, greatly reducing unnecessary friction and wear between the butterfly plate and the valve seat, reducing the opening resistance, and extending the service life of the butterfly valve.
- Low-pressure loss: The structure of the butterfly valve makes it have a lower pressure drop, and the resistance of the fluid passing through the valve is small, which can reduce the energy consumption of the system.
- Good regulation performance: The butterfly valve has a large adjustment range and accuracy, which can meet the precise control requirements of the process for flow.
- Fast closing and starting: The design of the butterfly valve enables it to close and start quickly, and the valve can be fully opened and closed in a short time.
- Good corrosion resistance: The butterfly valve is made of corrosion-resistant materials and can adapt to the working environment of various media.
- Simple structure and small size: The butterfly valve has a simple structure, and small size, and is easy to install and maintain.
- Good sealing performance: The butterfly valve adopts a double-eccentric design, has good sealing performance, and can achieve a zero leakage working state.
- Easy to operate: Equipped with a self-locking gearbox and a mechanical indicator, it is easy to operate.
The double-eccentric flanged butterfly valve adopts a double-eccentric structure where the valve stem and the centerline of the valve seat are not aligned with the centerline of the butterfly plate, creating an eccentric design. This design significantly reduces friction between the valve disc and the valve seat, enhancing the valve's service life and sealing performance. Meanwhile, the use of a flanged connection ensures a reliable connection between the valve and the piping, making it suitable for high-pressure and large-diameter piping systems.
1. Valve body material: The valve body is available in various materials, including cast iron, carbon steel, and stainless steel, to meet the requirements of different working conditions. Users can select the most suitable valve body material based on the specific application scenario and media characteristics.
2. Rated pressure and diameter: The rated pressure range of the double-eccentric flanged butterfly valve is typically between tens of megapascals to hundreds of megapascals. The rated diameter generally ranges from a few millimeters to several meters, depending on the actual requirements.
3. Valve seat material: To ensure good sealing performance, the valve seat of the double-eccentric flanged butterfly valve is usually made of wear-resistant and corrosion-resistant materials such as polytetrafluoroethylene (PTFE) or ethylene propylene diene monomer (EPDM). These materials exhibit excellent wear resistance and corrosion resistance, effectively handling various media challenges.
4. Actuation methods: The double-eccentric flanged butterfly valve can be actuated in various ways, including manual operation, electric operation, and pneumatic operation. Users can choose the appropriate actuation method based on their specific needs to meet the control requirements in different application scenarios.
5. Operating temperature range: The operating temperature range of the double-eccentric flanged butterfly valve is typically between -40℃ and +200℃, but the specific range depends on the choice of valve body and sealing materials. Users should ensure that the selected valve can operate normally in their working environment.
6. Leakage class: The leakage class of the double-eccentric flanged butterfly valve is usually zero leakage or seal leakage level, indicating that the valve can effectively prevent media leakage in the closed state, ensuring the safe operation of the piping system.
Double-eccentric flanged butterfly valves are widely used in piping systems in various industries such as petroleum, chemicals, pharmaceuticals, food processing, and water treatment to control the flow rate and pressure of media. Their excellent performance and wide range of applications make them an indispensable component in these industries.
