Flanged Premium 100 gate valve EN 558-2 S.14/DIN F4. For water and neutral liquids to max. 70° C

AVK Premium 100 gate valves are built to last a century. They feature the renowned AVK gate valve design and offer full traceability of materials and test records. The stem of duplex stainless steel and thrust collar and wedge nut of Silicon-brass ensure exceptional wear protection, and the external PUR coating provides ultimate corrosion protection. As for all AVK gate valves for water, the wedge is fully vulcanised with AVK’s own drinking water approved EPDM rubber compound, and features an outstanding durability due to the ability of the rubber to regain its original shape, the double vulcanization process and the sturdy wedge design.
