Double eccentric butterfly valve to EN 593 w. SS seat and IP68 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.

Variant 756/106-682
Connection:	Flanged
Material:	Ductile Iron
DN:	DN700 - DN2800
PN:	PN10/16
Closing direction:	Clockwise to Close

Features

The tilted disc releases the compression of the disc sealing after a few degrees of opening resulting in low operating torque
The disc seal profile and rubber quality ensure low closing torques
All rubber parts are multi approved
Seal retainer ring of stainless steel
The threaded bolt holes in the disc are corrosion protected with O-rings
Replaceable seat ring of stainless steel fixed with bolts sealed with epoxy and sealed with an O-ring
Shaft of stainless steel AISI 431 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
Replaceable shaft sealing with two EPDM O-rings on each side of a bronze bushing, and a flat NBR gasket
DN 700-1600, body and disc coated with fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901, GSK approved, blue RAL 5017, according to WRAS-DVGW/W270/UBA
DN ≥ 1800, body and disc coated with 2-pack epoxy, blue RAL 5017 externally, ribbon blue or cream white internally, according to WRAS
