Pneumatic triple eccentric hard seal butterfly valve

Pneumatic triple eccentric hard seal butterfly valve

Brief description: 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.
