Resilient seated gate valve with flanged ends, 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 stem seal system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.

Variant 55/67-003
Connection: Flanged
Material: Ductile Iron
DN: DN700 - DN1000
PN: PN 16
Closing direction: Clockwise to Close

Features

  • Fixed, integral wedge nut prevents vibration
  • Polyamide wedge shoes protect the wedge rubber and provide low operating torque
  • Stainless steel stem and brass wedge nut for high corrosion resistance
  • Wedge rubber in drinking water approved EPDM
  • A large conical stem hole in the wedge prevents stagnant water from accumulating inside the valve
  • Three independent stem seals: outermost a wiper ring protects against pollution entering from the environment, it is backed up by the two O-rings surrounding the radial bearing and innermost the main hydraulic seal to the flow consists of one or two O-rings
  • Thrust bearing consisting of stainless steel discs coated with a low friction, self-lubricating bronze-PTFE composite
  • Round bonnet gasket fixed in a recess to avoid blow out
  • Counterbored A2-70 stainless steel bonnet bolts encircled by the bonnet gasket and sealed with hot-melt glue
  • ISO actuator flange; electric actuator or gearbox is recommended
  • 3/4" connection plug for installation of air valve
  • Integrated lifting eyes for easy handling
  • Coating in 250 µm blue RAL 5017 fusion bonded epoxy (FBE) to GSK and DIN 3476
  • Installation with horizontal or vertical stem
  • By-pass valve, AVK 21/35 DN100
  • Removable gland flange for replacement of thrust- and radial bearings and seals under pressure
  • Detachable covers at the bottom for flushing of wedge rail
