Metal sealed electric butterfly valves have the structure of 3D eccentric metal sealed, whose seal mode is metal-to-metal, also can be changed into the other seal modes such as the metal seal ring to the metal, and the stainless steel plate seal ring or the graphite composite plate seal ring to the metal. This 3D eccentric metal seal butterfly valve with high performance is a device to regulate and cut off the medium of those piping in petroleum, chemical, power, metallurgy and city heat supply system.
*High temperature resistance, good seal performance, zero leakage.
*Small opening torque, no frictional rotation, long service life.
*Small volume, light weight, quick switch.
*The patent positioning technology.
*Replacing the body material, the different seal ring is suitable for different medium.
*Simple structure, easy to operate, high cost-effective.
*More than 50, 000 operation life without fault, keep your system operating safely and reliably.
