WKT's double-eccentric wafer-type butterfly valve is famous for its unique double eccentric design, one of which is that the valve stem axis deviates from the center of the butterfly plate, and the other is that the valve plate center deviates from the center of the body. 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 distance, and extending the service life of the butterfly valve.
The double-eccentric wafer-type butterfly valve features a double-eccentric design, where the centerline of the stem and the seat does not align with the centerline of the disc. This eccentric design reduces friction between the disc and the seat, enhancing the valve's service life and sealing performance. Additionally, the wafer-type connection allows the valve to be clamped directly into the pipeline, eliminating the need for additional flange connections, resulting in simplified installation.
1. Body material: Common materials include cast iron, carbon steel, stainless steel, and others. Suitable valve body materials can be selected based on different working conditions.
2. Rated pressure and diameter: The rated pressure range of the double-eccentric wafer-type butterfly valve is typically between several tens of megapascals to several hundred megapascals, with rated diameters ranging from several millimeters to several meters.
3. Seat material: The seat of the double-eccentric wafer-type butterfly valve typically utilizes wear-resistant and corrosion-resistant materials such as poly tetra fluoro ethylene (PTFE) and ethylene propylene diene monomer (EPDM) to ensure excellent sealing performance.
4. Actuation methods: The double-eccentric wafer-type butterfly valve can be actuated manually, electrically, pneumatically, or via other methods, allowing for the selection of a suitable actuation method based on actual needs.
5. Operating temperature range: The operating temperature range of the double-eccentric wafer-type butterfly valve is generally between -40℃ to +200℃, with the specific range depending on the choice of valve body and sealing materials.
6. Leakage class: The leakage class of the double-eccentric wafer-type butterfly valve is typically zero leakage or a sealed leakage class, ensuring excellent sealing performance in the closed state.
- Compact structure and easy installation and disassembly: The double eccentric butterfly valve has a reasonable design, and compact structure, and is easy to install and maintain.
- Reduced friction of the sealing ring: Due to the eccentric structure, the friction of the sealing ring is reduced and the service life of the valve is extended.
- Completely sealed, zero leakage: The double eccentric butterfly valve can achieve complete sealing and is suitable for ultra-high vacuum conditions.
- Applicable to a variety of media and temperatures: By changing the materials of the valve plate seal, butterfly plate, shaft, etc., the double eccentric butterfly valve can be applied to a variety of media and different temperatures.
- Flexible operation: The design of the double eccentric butterfly valve requires less force when opening and closing, making it more flexible and convenient to operate and suitable for automatic control systems.
- Small size and lightweight: Compared with other types of valves, the double eccentric butterfly valve has a smaller size and lighter weight, which is easy to install and maintain.
- Long service life: Due to uninterrupted anti-corrosion protection and high-quality components, the double eccentric butterfly valve has a long service life.
The double-eccentric wafer-type butterfly valve is widely used in pipeline systems in industries such as petroleum, chemicals, pharmaceuticals, food processing, and water treatment to control the flow and pressure of media.
