Water-cooled type high temperature butterfly valve is a kind of used for high temperature pipelines using special butterfly valve, high quality heat resistant steel, valve plate inner chamber is cooled, the advantages of low water consumption, high temperature resistant, long service life, convenient operation and maintenance, flexible rotation, etc, and can be all kinds of electric actuators, realize remote control and automatic adjustment and cut, are widely used in metallurgy, chemical industry, building materials, plant and other ultra high temperature of the gas pipeline, used as a medium flow control and cut off.
It is mainly composed of valve body, valve rod, butterfly plate and sealing ring. The valve body is cylindrical with short axial length and built-in butterfly plate. The driving mode is driven by electric or pneumatic actuator.
