WKT's multi-layer hard seal flange butterfly valve adopts innovative multi-layer hard seal technology, which can provide efficient sealing performance under various extreme working conditions. Such butterfly valves are usually made of temperature-resistant and corrosion-resistant materials, such as stainless steel or alloy steel, and their sealing surfaces are usually coated with wear-resistant materials, such as tungsten carbide or cemented carbide, to enhance durability.
- Enhanced sealing performance: Multi-level sealing design ensures zero leakage under different pressures and temperatures.
- High temperature and high-pressure resistance: The selected materials and design enable the valve to work stably under high-temperature and high-pressure environments.
- Corrosion resistance: The materials of the butterfly valve body and sealing surface can be selected according to the characteristics of the medium to resist corrosion.
- Wear resistance: The sealing surface is surfacing with materials such as hard alloy, which increases the wear resistance of the butterfly valve.
- Easy maintenance: Reasonable structural design facilitates on-site maintenance and component replacement.
This type of butterfly valve is widely used in pipeline systems in petroleum, chemical, metallurgy, electric power, water conservancy, and other industries to regulate or cut off the flow of media.
1. Three-eccentric structure: The three-eccentric structure design makes the butterfly valve seat and the butterfly plate almost frictionless, with a sealing performance that becomes tighter and tighter as it is closed, achieving zero leakage.
2. Hard and soft multi-layer seal: The butterfly plate seal is a hard and soft multi-layer, with the advantages of hard and soft double seals, and has excellent sealing performance regardless of low or high-temperature conditions.
3. Corrosion resistance and high-temperature resistance: The butterfly valve seat and butterfly plate sealing surfaces are made of different hardness and stainless steel materials, with good corrosion resistance and long life.
4. Bidirectional sealing function: It has a bidirectional sealing function, and the installation is not restricted by the flow direction of the medium, and can be installed in any direction.
5. Small opening and closing torque: Flexible operation, labor-saving and energy-saving, and long service life.
6. Wide range of application: Suitable for a variety of media such as water, steam, oil, etc., with a wide range of operating temperatures, from -29℃ to 425℃.
7. Self-cleaning ability: It has a certain self-cleaning ability, suitable for steel plant sewage pipes, municipal pipelines, etc., showing many advantages.
1. Pre-installation inspection: Before installation, check whether all parts of the butterfly valve are complete and confirm that the butterfly valve is not damaged, especially the sealing surface and butterfly plate.
2. Installation direction: Confirm the installation direction of the butterfly valve and ensure that the medium flow direction is the same as the rotation direction of the butterfly plate to obtain the best sealing effect.
3. Drive device setting: The butterfly valve is a quarter-turn valve and can be operated by a handle, manual gear, pneumatic actuator, or electric actuator. Make sure the stroke limit of the actuator is set correctly to achieve full closure.
4. Operation limit: High-performance butterfly valves must be operated within a defined quadrant because a hard stop is integrated into the valve body. Therefore, the butterfly disc always closes in a clockwise direction, and the manual or automatic operator must be set accordingly.
5. Maintenance and inspection: Perform maintenance and inspection regularly to ensure the sealing and operating performance of the valve. Check and replace worn parts such as packing and seals.
