AVK Singapore Pte. Limited, 40 Gambas Crescent Nordcom 2 757018 Singapore Singapore

Swing check valve, resilient seated with free shaft end. For drinking water and neutral liquids to max. 70°C

AVK series 41 swing check valves come with both metal and resilient seats. Installed in pumping applications to prevent back flow they can be used for drinking water as well as waste water. The disc is connected to the shaft via a flexible bush that allows disc and valve seat to adjust exactly. All interior parts are stainless steel or coated with drinking water approved epoxy or EPDM. The series 41 valves are available with either closed bushings or protruding shaft end where a lever with a weight or a spring can be fitted to mitigate pressure surges.

Variant 41/60-003
Connection: Flanged
Material: Ductile iron
DN: DN50 - DN300
PN: PN 16

Features

  • Clear way and full bore for low head loss and easy pig-cleaning

  • Shaft fitted in the bonnet allowing for easy maintenance without removing valve from pipeline
  • Shaft in 1.4021 (AISI 420)  stainless steel
  • Free protruding shaft end for mounting of lever and weight or spring to assist valve closing and avoid water hammer

  • Ductile iron disc covered with drinking water approved EPDM
  • Bonnet gasket lying in a groove between bonnet and body prevents blow-out
  • All seals and coatings with contact to the fluid are approved for drinking water - coating is blue, 250µm fusion bonded epoxy
  • Disc is designed with a steel insert fully vulcanized with EPDM rubber
  • Bosses on each side of the valve seat allow for installation of pressure gauge, by-pass, etc.
