4. Characteristics
Butterfly valves are designed for general use pipelines in industrial systems, for the second group of fluids. They are designed to cut off as well as control the flow of drinking and industrial water, steam, air. They are also used in the power industry, heat engineering, chemical industry (for non aggressive and non toxic liquid and gas substances), petrochemical and refinery industries, coke and chemical industry (coke-oven gas). They can be installed on pipelines in any position.
