Product Manager, butterfly valves
Double eccentric butterfly valve to EN 593 w. integral seat and IP67 gearbox w. handwheel, position indicator and internal enamel. 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 / internal enamel and the corrosion protected shaft end zones ensure high durability. The valves are suitable for bi-directional application.
