electric PTFE butterfly valve

 

Product Name: Electric Butterfly fluorine
 Product Overview
 The company's Shanghai-brand electric Lining Butterfly River (also known as corrosion-resistant electric butterfly valve) and by the electric actuator composed of fluorine Butterfly Valves, Butterfly Valves are used with the rotation of the disc valve stem to open and close documents to achieve the valve open, close and adjust. Electric fluorine flow components in the valve, the valve body, disc, stem thick lining on the use of lining technology polymer materials, excellent corrosion resistance, corrosion resistance, electric butterfly valve apply to any concentration of acid, alkali , salt and oxidants, reducing agents, organic solvents such as media, chemical, petroleum, pharmaceutical, food, iron and steel smelting, paper, water and other systems of gas, liquid, semi-fluid piping and containers used for the closure and conditioning equipment ideal, and can replace the valve, the valve and other types of cut off, adjust the valves.
 Factory production of electric fluorine butterfly, with a corrosion-resistant, leak-free, long lifetime. Butterfly valve for electric fluorine concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid and various organic acids, strong acids, oxidizing medium, or high-temperature en-sulfuric acid, hot concentrated acetic acid, pH and a variety of alternating strong organic solvents and other corrosive the media.
