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.

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. The valves are suitable for bi-directional application.

  • Double eccentric design 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
  • 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
  • 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
