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 stem seal system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.
