The AVK Model N7 Above Ground Multi Hydrant with traffic break-away design (Type C) and double shut-off is available with multiple configurations. The heavy duty materials with extra corrosion protection, the PUR coated disc with high memory effect and the high flow capacity ensure durability and good performance. Series 84/93 is designed with double shut-off system for a continued sealing of the hydrant during maintenance, and with traffic break-away design. The flanges connecting the upper and lower barrel are assembled with special stainless steel bushes designed to break if something hits the hydrant. These bushes are the only spare parts to be replaced in case of a breakdown.
