China Triple Eccentric Metal Seated Butterfly Valve - Quality Suppliers and Factory Direct Prices

The three eccentric butterfly valve operates on a unique structural design that optimizes sealing and flow control through its three eccentric distances, **Structural Design: Three Eccentric Structure**: The valve stem axis is intentionally offset from the center of the butterfly plate and the valve body’s center. Additionally, the rotation axis of the valve seat is angled relative to the valve body channel axis. This innovative design allows the butterfly plate to create a wedge-shaped space with the valve seat when closed, effectively achieving a reliable seal through friction, **Conical Sealing Surface**: The butterfly plate features an external inclined conical surface, while the valve seat is designed with an internal inclined conical surface, resulting in an elliptical contact area. When the valve is closed, the asymmetric pressing force applied in both vertical directions enhances the sealing capability, becoming increasingly secure as the pressure rises, As a leading manufacturer and supplier from China, our factory ensures the production of high-quality three eccentric butterfly valves optimized for performance and durability.

    Product Description
    Working Mechanism
    Open State: The butterfly plate is separated from the valve seat, and the fluid passes through the channel; due to the eccentric design, during the opening process, the butterfly plate gradually detaches from the valve seat, reducing friction and operating torque.
    Closed State: The butterfly plate rotates 90° to contact the valve seat, forming a wedge-shaped space and achieving sealing through torque.
    Flow Regulation: During the opening rotation of the butterfly plate, the valve's flow area gradually increases, reducing fluid resistance and improving the flow coefficient, achieving flow regulation.
    Technical Advantages
    Sealing Performance: The metal-to-metal hard sealing method can still maintain good sealing performance in high-temperature and high-pressure environments.
    Low Friction Operation: The eccentric design significantly reduces the operating torque and extends the valve's lifespan.
    Self-Locking Function: When closed, the butterfly plate becomes tighter under pressure, preventing the phenomenon of over-positioning.
    This valve is widely used in the petroleum, chemical, and power industries. Common structural connection forms include double flange type, welding type, lug type, and socket type, etc.

    Frequently Asked Questions (FAQ)
    Q: What are the main applications of the triple eccentric butterfly valve?

    It is widely used in the petroleum, chemical, and power industries, and is highly suitable for water, steam, oil, and gas applications.

    Q: How does the eccentric design benefit the valve?

    The eccentric design minimizes wear on the sealing surface during operation. It gradually detaches the butterfly plate from the valve seat when opening, which reduces friction, lowers operating torque, and significantly extends the valve's lifespan.

    Q: Can this valve withstand high temperatures and corrosive environments?

    Yes, it features a metal-to-metal hard seal and its sealing surface is coated with temperature and corrosion-resistant materials, making it highly reliable in various extreme temperatures, pressures, and corrosive conditions.

    Q: What happens when the butterfly valve is in the closed state?

    In the closed state, the butterfly plate rotates 90° to contact the valve seat, forming a wedge-shaped space. It achieves a tight seal through torque and utilizes a self-locking function to prevent over-positioning under pressure.

    Q: Does the valve offer flow regulation capabilities?

    Yes, during the opening rotation, the flow area gradually increases. This reduces fluid resistance and improves the flow coefficient, allowing for precise and effective flow regulation.

    Q: What types of structural connections are available?

    The valve is available in several common structural connection forms, including double flange type, welding type, lug type, and socket type to meet different installation requirements.
