Flanged gate valve, UL/FM approved for fire protection applications to max. 70°C water temperature. AWWA and FM rated working pressure 250 psi for all sizes, UL rated working pressure 200 PSI for DN400 & DN 350, and 250 PSI for the below remaining sizes
AVK gate valves are designed with build-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 trible safety stem sealing system, the high strength stem and the thorough corrosion protection safeguard reliability.
