Product Description Product Details: The electric flanged hard-sealed butterfly valve adopts a precision-engineered J-shaped elastic sealing ring and a triple eccentric multi-layer metal hard sealing structure. It is widely used in industrial pipelines with medium temperatures ≤425°C, such as in metallurgy, power generation, petroleum, chemical industries, as well as water supply, drainage, and municipal construction, serving to regulate flow and cut off fluids. Performance Features:Triple-Eccentric Sealing StructureThis valve adopts a triple-eccentric sealing structure, ensuring minimal wear between the valve seat and the disc. The sealing function becomes tighter as the valve closes.Dual Advantages of Metal and Elastic SealingThe sealing ring is made of stainless steel, offering the combined benefits of metal hard sealing and elastic sealing. It delivers excellent sealing performance under both high and low temperatures, while being corrosion-resistant and ensuring a long service life.Corrosion-Resistant and Durable Sealing SurfaceThe disc sealing surface is welded with cobalt-based hard alloy, making it resistant to corrosion and significantly extending its service life.Bidirectional Sealing FunctionalityThe valve supports bidirectional sealing, making it unaffected by the medium's flow direction or spatial installation position. It can be installed in any orientation.

Question:What is a three eccentric butterfly valve? Answer:Triple eccentric butterfly valve is a fluid control valve commonly used in industrial pipelines, and its structure is divided into three aspects of eccentricity:1. The centerline of the valve body does not coincide with the centerline of the sealing surface;2. The centerline of the valve stem does not intersect with the sealing surface;3. The axis of the valve plate cover does not coincide with the centerline of the valve body and the centerline of the valve stem.2. Question:Does the three eccentric butterfly valve have directional issues? Answer:A three eccentric butterfly valve is a one-way flow valve that typically requires the direction of the arrow on the valve body to be the same as the flow direction of the medium. Therefore, the three eccentric butterfly valve can be said to have directional issues, and incorrect direction can lead to poor valve performance.
