Product Description
Electric double eccentric 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.
