Double eccentric butterfly valve to EN 593 for neutral liquids like drinking water and treated waste water free from solids and fibrous impurities to max 70°C. Sizes up through DN2400 are suitable for bi-directional application, DN2600 and above must be operated uni-directionally.

AVK double eccentric butterfly valves with tilted disc are designed for easy operation and long service life. The disc seal is made of AVK's drinking water approved EPDM rubber featuring an excellent compression set and ability to regain the original shape. The high quality epoxy coating and fully encapsulated shaft/disc connection ensure optimal corrosion protection and durability

Features

  • Double eccentric design releases 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 drinking water approved by multiple institutes
  • Fasteners in stainless steel, A2
  • Stainless steel shaft and seal retainer ring
  • Replaceable seat ring in stainless steel fixed with bolts and sealed with an O-ring
