Flanged gate valve with actuator flange and by-pass, 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 quadruple stem seal system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.

Variant 06/30-030
Connection: Flanged
Material: Ductile Iron
DN: DN700 - DN1200
PN: PN10/16
Closing direction: Clockwise to Close

Features

  • Wedge nut in dezincification resistant brass, designed as a fixed, integral part of the wedge which prevents vibration and ensures durability
  • Wedge and wedge nut fully encapsulated in drinking water approved EPDM
  • Wedge shoes in PA and guide rails on the body make the wedge slide easily up and down, keeping operational torque low even at high differential pressure
  • A large conical stem hole going all the way through the wedge ensures circulation and prevents accumulation of stagnant water
  • Stem in stainless steel with wedge stop and rolled threads for high strength
  • Full circle thrust bearing keeps the stem firmly lined up and ensures low operating torque. Sizes DN450 to DN600 have a double roller bearing and DN700+ have stainless steel washers coated with bronze/PTFE composite
  • Three independent stem seals: an NBR wiper ring protects against contamination from outside, four O-rings surround the radial bearing and innermost a lip seal backed up by an O-ring act as the main seal to the flow
  • Bonnet gasket with a circular cross section fixed in a recess to avoid blow-out
  • Bonnet bolts in A2-70, counterbored, sealed with hot melt glue and encircled by the bonnet gasket
  • Corrosion protected with fusion bonded epoxy, applied in a GSK approved process, blue RAL 5017
  • A by-pass valve is fitted to ease operation at high differential pressure
  • ISO actuator flange; gearbox or actuator is recommended
  • Detachable covers at the bottom for flushing of wedge rail
