EB3026 Electric Butterfly Valve

EB3026 Electric Butterfly Valve
Product Overview
The EB3026 Electric Butterfly Valve, as a component used to achieve on/off control and flow regulation in pipeline systems, has been widely applied in many fields such as HVAC, petroleum, chemical, metallurgy, and hydropower. In known butterfly valve technologies, the sealing form mostly adopts a sealing structure with materials like rubber and polytetrafluoroethylene. Due to structural limitations, it is not suitable for industries requiring high temperature, high pressure, corrosion resistance, and wear resistance. A relatively advanced butterfly valve is the triple eccentric metal hard seal butterfly valve, where the valve body and seat are integrated components, and the sealing surface layer of the valve seat is overlay welded with temperature-resistant and corrosion-resistant alloy materials. The multi-layer soft stacked sealing ring is fixed on the disc. Compared to traditional butterfly valves, this valve offers advantages such as high temperature resistance, easy operation, friction-free opening and closing, and improved sealing performance and extended service life through torque compensation during closing via the transmission mechanism.

Product Features
1. The valve adopts a double eccentric structure, providing a sealing function that tightens as it closes, ensuring reliable sealing performance.
2. The sealing pair materials are stainless steel and oil-resistant rubber, offering a long service life.
3. The rubber sealing ring can be located on either the valve body or the disc, making it suitable for media with different characteristics, providing options for users.
4. The disc uses a frame structure, offering high strength, large flow area, and low flow resistance.
5. The entire valve is painted, effectively preventing rust, and by simply replacing the sealing material of the valve seat, it can be used for different media.
6. The valve features bidirectional sealing functionality, and its installation is not constrained by the flow direction of the medium or spatial position, allowing installation in any direction.
7. The valve has a unique structure, offering flexible, labor-saving, and convenient operation.
