Double eccentric butterfly valve to EN 593 for neutral liquids like drinking water and treated waste water free from solids and fibrous impurities to max 70°C.

AVK double eccentric butterfly valves with tilted disc are designed for easy operation and long service life. The disc seal is made of AVK's drinking water approved EPDM rubber featuring an excellent compression set and ability to regain the original shape. The high quality epoxy coating and fully encapsulated shaft/disc connection ensure optimal corrosion protection and durability
