Features

KVGD9012-2.5P electric high tempertaure butterfly valve is a new generation of high temperature valve in the introduction of foreign advanced technology, combined with the domestic manufacturing process development. It is widely used in the high temperature gas pipelines of metallurgy, building materials, chemical industry, power plants, glass and other industries, as the device of cutting off or regulating high-temperature gas medium flow, it can be paired with a variety of actuators to make up different performance devices. The body and the disc use high-quality materials, made of heat-resistant steel. It has characteristics of high temperature resistance, small size, flexible rotation, long service life, convenient operation and maintenance and so on.
