Overview and Application
The sealing surface of the pneumatic triple eccentric hard seal butterfly valve is evenly stressed and has high pressure bearing capacity in the closed state. It is widely used in chemical, electric power, metallurgy, air separation and other industries. It is widely used in corrosion, high temperature and high pressure working conditions. Liquids, gases, steam and high-viscosity media Gases and media are abrasive.
