Double eccentric butterfly valve to EN 593 w. integral seat and IP67 gearbox w. handwheel for drinking water and neutral liquids to max. 70°C

AVK double eccentric butterfly valves are designed with tilted and fixated disc for extended service life and 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 GSK/WRAS approved epoxy coating and fully encapsulated shaft/disc connection ensure high durability. The valves are suitable for bi-directional application.                


















Variant 756/118-001
Connection: Flanged
Material: Ductile Iron
PN: PN 10/16
Closing direction: Clockwise to Close


The tilted disc releases the compression of the disc sealing after a few degrees of opening, which extends the durability and gives low operating torques

The disc is fixated to prevent wear and fluttering

The disc seal profile and rubber quality ensure low closing torques

Seal retainer ring of stainless steel

The threaded bolt holes in the disc are corrosion protected with O-rings

Machined and epoxy coated ductile iron seat integrated in the body

Shaft of stainless steel with self-lubricating bearings

The shaft ends are fully encapsulated in the disc and are fixed with dowels corrosion protected with O-rings and a stainless steel security plate. Key and keyway as backup.
