Henrik Steen Christensen
Product Manager, butterfly valves
Double eccentric butterfly valve to EN 593 w. integral 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 DVGW/WRAS approved epoxy coating and fully encapsulated shaft/disc connection ensure high durability. The valves up to DN2400 are suitable for bi-directional application, DN2600 and above must be operated uni-directional.
