The hard-seated triple eccentric flange butterfly valve achieves a near-zero leakage sealing effect through its unique three-eccentric structure (two eccentricities of the valve stem and one eccentricity of the valve seat). Hard-seated means that the sealing surfaces of the valve seat and valve plate are made of hard materials such as stainless steel, tungsten carbide, or special alloys to ensure durability and sealing under extreme conditions.
- Triple eccentric structure: The triple eccentric design of the valve stem and valve seat achieves zero friction when the valve is opened and closed, reduces the operating torque, and improves the sealing reliability.
- Hard seal material: The sealing surface usually adopts a metal-to-metal hard seal, such as stainless steel, alloy material, or other high-temperature-resistant and wear-resistant materials, which are suitable for high-temperature, high-pressure, and corrosive media.
- Durability: Due to the reduction of friction on the sealing surface, the durability and reliability of the valve have been greatly improved, especially suitable for occasions with frequent operation.
- Easy maintenance: The structure is simple and maintenance is convenient, and suitable for various industrial environments, especially those requiring a long-term reliable operation.
- Multiple drive modes: It can be equipped with manual, electric, pneumatic, or hydraulic drive devices to meet different operating requirements.
A hard-seal triple eccentric flange butterfly valve is widely used in petroleum, chemical, electric power, metallurgy, heating, and gas supply, and water treatment industries, especially suitable as a key equipment for cutting off and regulating pipelines with high temperature, high pressure, or containing solid particle media.
1. How to ensure the structural safety of the hard-seal triple eccentric flange butterfly valve?
By optimizing the material distribution and structural size parameters of the valve body assembly, the sealing pressure can be adjusted to achieve a long-term and effective sealing effect.
2. How does the hard-seal triple eccentric flange butterfly valve deal with wear and corrosion?
The sealing effect can be improved by increasing the interference of the sealing surface and improving the material strength of the sealing surface.
3. What is the maintenance cost of the hard-seal triple eccentric flange butterfly valve?
The sealing assembly of the butterfly valve is split, and the new valve seat can be directly disassembled and replaced, which reduces the maintenance cost.
