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.
