AVK gate valve, flanged, PN10

EN558-14/DIN F4, SS stem, DN700-800


AVK International A/S

Bizonvej 1, Skovby, 8464 Galten, Denmark

Flanged gate valve EN 558-2 S.14/DIN F4. 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 EPDM rubber compound with WRAS and DVGW W270 drinking water approval. 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 sealing system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.

Variant 06/30-026

  • Fixed, integral wedge nut prevents vibration and increases durability 
  • Polyamide wedge shoes protect the wedge rubber during opening and closing 
  • Stainless steel stem with wedge stop 
  • A large conical stem hole in the wedge prevents stagnant water 
  • Four independent stem seals: outermost an NBR wiper ring protects against pollution from the environment, next the polyamide radial bearing is surrounded by two NBR O-rings followed by another O-ring around the stem and innermost an EPDM lip seal is the main hydraulic seals to the flow
  • Axial thrust bearing with stainless steel washers coated with fiber reinforced PTFE provides low operating torque 
  • Removable gland flange for replacement of thrust- and radial bearings and seals under pressure 
  • Round bonnet gasket fixed in a recess to prevent blow-out
  • Counterbored stainless steel bonnet bolts encircled by the bonnet gasket and sealed with hotmelt glue 
  • ISO actuator flange; electric actuator or gearbox is recommended 
  • Integrated lifting eyes for easy handling 
  • 3/4" connection plug for installation of air valve 
  • Fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901, GSK approved
  • All rubber parts with multiple drinking water approvals (DVGW, WRAS) 
  • For installation with horizontal or vertical stem 
  • Detachable covers at the bottom for flushing of wedge rail 
  • Bosses prepared for by-pass valve
