Structural features and uses
This valve is a kind of ideal equipment for gas switching. It is developed by our factory which absorbs the advanced technology of similar products at home and abroad. The valve has the advantages of simple structure, convenient operation, reliable sealing, accurate switching and long service life. It is widely used in metallurgy , Petrochemical, environmental protection and other industries on-site operation or long-distance control. It is especially suitable for the recovery and dissipation of controlled gas in the converter gas recovery unit of steel plant. The valve is mainly composed of three bodies and two sealed butterfly valve and two gas (oil) cylinder, connecting rod, control box.
