Product Manager, butterfly valves

Double eccentric butterfly valve to EN 593 w. integral seat and ISO-input IP67 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 GSK approved epoxy coating and the corrosion protected shaft end zones ensure high durability. The valves are suitable for bi-directional application.

Variant 756/102-142
Connection: Flanged
Material: Ductile Iron
DN: DN150 - DN600
PN: PN10/16

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 epoxy coated 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 corrosion protected with a stainless steel security plate and a gasket
  • Replaceable shaft sealing with an EPDM O-ring on a stainless steel ring, a back-up EPDM O-ring in the housing, and a flat NBR gasket
