How to change the French electric three eccentric butterfly valve to manual? Fluoropolymer can extend the service life of valves. A new butterfly valve with PTFE lining can be used as 8 times as long as similar valves are used with traditional service and monomer fluid lining materials, as reported by DuPont. Valve, 4 inch (102 mm) by GarSeal Valve (Town, PA) unit uses [deg] ℃ (- 2 [deg] f in DuPont Dow) elastomer plants in receiving liquid neoprene - 18 applications. According to DuPont, compared with the traditional material "lining valve failure chloroprene is faster because it penetrates the lining and makes it expand." Because of the high creep resistance and
、 The development of enterprises must be able to have very long-term goals. Because in the process of development, we must be able to keep moving forward to avoid being eliminated by the cruel market. In the development of electric butterfly valves, we need to be able to base ourselves on domestic development, and then let ourselves go to the international market. So, what do we need to do to achieve such development goals?
