China Triple Eccentric Metal Seated Butterfly Valve - Reliable Design from Leading Suppliers & Factory
Unique, compact, and lightweight design with flexible and labor-saving operation.
Provides reliable sealing that meets various standards.
Offers good flow characteristics and has a regulating function.
Utilizes an eccentric design to minimize wear on the sealing surface, extending the valve's lifespan.
Suitable for a wide range of applications, including water, steam, oil, and gas.
Applicable across various conditions including different temperatures, pressures, and corrosive environments.
Features a triple eccentric hard-sealed butterfly valve with an integral body and seat, the seat's sealing surface is coated with temperature and corrosion-resistant materials.
Three eccentricities position the shaft and sealing surfaces to optimize sealing and reduce wear.
Equipped with multi-layer sealing rings on the valve plate, enhancing sealing performance and operational ease, suitable for both high and low temperatures, ensuring zero leakage.
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.
The butterfly plate rotates 90° to contact the valve seat, forming a wedge-shaped space and achieving sealing through torque.
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.
The metal-to-metal hard sealing method can still maintain good sealing performance in high-temperature and high-pressure environments.
The eccentric design significantly reduces the operating torque and extends the valve's lifespan.
When closed, the butterfly plate becomes tighter under pressure, preventing the phenomenon of over-positioning.
It is widely used in the petroleum, chemical, and power industries, and is highly suitable for various applications including water, steam, oil, and gas.
The eccentric design minimizes wear on the sealing surface, significantly reduces friction and operating torque during opening and closing, and extends the overall lifespan of the valve.
Yes, it utilizes a metal-to-metal hard sealing method and the seat's sealing surface is coated with temperature and corrosion-resistant materials, making it perfectly applicable across extreme temperatures, high pressures, and corrosive conditions.
In the closed state, the butterfly plate rotates 90° to contact the valve seat, forming a wedge-shaped space. This achieves a tight seal through torque and features a self-locking function that prevents over-positioning.
Yes, during the opening rotation of the butterfly plate, the valve's flow area gradually increases, which reduces fluid resistance and improves the flow coefficient, effectively achieving precise flow regulation.
Common structural connection forms for this valve include the double flange type, welding type, lug type, and socket type, providing flexibility for different installation requirements.
