Double eccentric butterfly valve with 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 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.

Variant 756/100-104
Connection: Flanged
Material: Ductile Iron
DN: DN150 - DN600
PN: PN10/16

Features

  • Machined and epoxy coated ductile iron seat integrated in the body
  • The double eccentric design combined with a tilted disc allows release of seal compression after only few degrees of opening resulting in low operating torque 
  • Disc firmly fixed to the shaft to prevent fluttering and a slight tilt allows for precise adjustment of the closed position
  • Disc seal profile and rubber quality ensure low closing torque
  • All rubber parts are drinking water approved by multiple institutes
  • Fasteners in stainless steel A2
  • Stainless steel shaft and seal retainer ring
  • All threaded connections are sealed with O-rings for protection against medium and environment
  • Radial bearings in self-lubricating PTFE/bronze composite
  • Shaft ends: DN≤600: Fitted with an end cover that seals the disc interior against corrosion. DN≥700: Fully encapsulated in the disc and fixed with O-ring sealed dowels held in place with a security plate. Key and keyway as backup
  • Replaceable shaft seals with two EPDM O-rings and an NBR gasket protecting against contamination from outside
  • Body and disc of ductile iron with fusion bonded epoxy coating 250µm RAL 5017 in compliance with DIN 3476 part 1 and EN 14901, approved by GSK and WRAS-DVGW/W270/UBA
  • IP67 Rotork gear with position indicator, operated by handwheel. Coated black RAL9005, 50-60µm. Input shaft, bolts and nuts in stainless steel AISI 303
