Double eccentric butterfly valve to EN 593 w. integral 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 epoxy coating and fully encapsulated shaft/disc connection ensure high durability. The valves are suitable for bi-directional application. The 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.

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
  • 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
