Electric three eccentric flange butterfly valve
The Electric Triple Eccentric Flange Butterfly Valve is an advanced high-performance valve designed for demanding industrial applications requiring reliable shut-off, precise flow control, and long service life. Featuring a triple eccentric structure combined with an electric actuator, the valve provides excellent sealing performance, low operating torque, and outstanding resistance to high temperature, high pressure, and corrosive media.
The triple eccentric design eliminates friction between the sealing surfaces during operation, significantly reducing wear and extending valve service life. The metal-to-metal sealing system ensures reliable zero-leakage performance and makes the valve ideal for harsh operating conditions where conventional butterfly valves cannot meet performance requirements.
Equipped with an electric actuator, the valve supports remote operation, automatic control, and integration with PLC, DCS, and SCADA systems. It is widely used in oil & gas, power generation, chemical processing, metallurgy, petrochemical, and industrial pipeline systems.
