More Information
Summary:The invention provides a clip-type high-temperature and highly corrosion resistant butterfly valve. In the existing valve, the pivot connects with the butterfly board machinery. There is closed stainless steel material on the butterfly board. The butyl clip plumbago layer is treated with special technique during the production, is featured by high temperature resistance, corrosion resistance and long useful life and is adaptable to the impingement from the liquid with low-middle pressure. It is featured by large circulation area, small coefficient of flow resistance, compact structure, beautiful appearance, small volume, light weight, minimum open and close moment, simple installation and maintenance and flexible operation and can replace the gate valve and the break valve. It is widely applied to: petrifaction, coal gas, natural gas, thermoelectricity, hydraulic power plant, municipal construction, tap water, pharmacy, food and other projects and especially to the pipeline transportation with zero leakage.
