Flanged gate valve for 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, featuring an outstanding durability due to the ability of the rubber to regain its original shape combined with a double bonding vulcanization process and a sturdy wedge design. A triple stem sealing system, SS 4404 stem and the thorough corrosion protection safeguard the unmatched reliability.

Features
- Wedge nut firmly fixed in the wedge as an integral part to prevent vibration
- Wedge fully vulcanized in drinking water approved EPDM and fitted with wedge shoes that protect the rubber and provide low operating torque
- Stem in SS 4404/316L and brass wedge nut for high corrosion resistance
- 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 the environment, 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
- Round bonnet gasket fixed in a recess to avoid blow out
- Counterbored A4-70 stainless steel bonnet bolts encircled by the bonnet gasket and sealed with hot-melt glue
- ISO actuator flange; electric actuator or gearbox is recommended
- Coating in 300µm blue RAL 5017 fusion bonded epoxy (FBE)
- Installation with horizontal or vertical stem
- AVK 06/34 DN80 by-pass valve
- Removable gland flange for replacement of thrust- and radial bearings and seals under pressure
