Flanged gate valve with rising stem 1.4401 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 double safety stuffing box sealing system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.
