Double eccentric butterfly valve to EN 593 w. stainless steel seat and ISO-input IP67 gearbox for drinking water and neutral liquids to max. 70°C

AVK double eccentric butterfly valves are designed with tilted disc for easy operation. The disc seal is made of AVK’s drinking water approved EPDM rubber featuring an excellent compression set and thus ability to regain its original shape. The high quality GSK approved epoxy coating and the corrosion protected shaft end zones ensure high durability. The valves are suitable for bi-directional application.
