AVK GATE VALVE, FLANGED, PN10/16

EN558/3 (BS), SS stem, A2 bolts, hand wheel, pos. indicator, bracket for position sensor

Flanged gate valve for drinking water and neutral liquids to max. 70° C

AVK gate valves are designed with built-in safety in every detail. The wedge is fully vulcanized with AVK’s own drinking water approved EPDM rubber compound. It features an outstanding durability due to the ability of the rubber to regain its original shape, the double bonding vulcanization process and the sturdy wedge design. The triple safety stem sealing system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.

Variant 02/26-001
Connection: Flanged
Material: Ductile iron
DN: DN50 - DN400
PN: PN 16
Closing direction: Clockwise to Close

Features

  • Wedge nut designed as a fixed, integral part of the wedge which prevents vibration and ensures durability
  • Wedge core fully vulcanized with drinking water approved EPDM rubber in a sophisticated process that eliminates creeping corrosion underneath the rubber
  • Wedge shoes in PA and guide rails on the body make the wedge slide easily up and down regardless of differential pressure
  • A large conical stem hole going all the way through the wedge ensures circulation and prevents stagnant water
  • Stainless steel stem with wedge stop and rolled threads for high strength
  • Full circle thrust collar keeps the stem firmly lined up and ensures low operating torque
  • Triple safety stem seal with an NBR wiper ring outermost to protect against contamination from outside, in the middle four NBR O-rings around the radial bearing and innermost an EPDM lip seal as main seal to the system pressure
  • Handwheel and position indicator
  • Bracket for additional remote control position sensor or switch to indicate either fully open or fully closed
  • Bonnet gasket in EPDM with a circular cross-section, fixed in a recess to avoid blow-out
  • Counterbored stainless steel bonnet bolts, sealed with hot-melt and encircled by the bonnet gasket
  • Full bore
  • 250 µm fusion bonded epoxy coating to DIN 3476
