Above-ground hydrants with unique features
Predetermined breaking point
We offer a wide range of above-ground hydrants characterised by a high level of safety. The specially designed and predetermined breaking point leaves both the hydrant and the pipeline undamaged in case of an accidental traffic knock down. The connection between upper and lower barrels allow for a 360° rotation of the upper barrel including the hydrant head. The flanges are assembled with special titanium bushes designed to break if something hits the hydrant.
The gear is placed below the breaking point and the above-ground hydrant is equipped with an additional ball shut-off. This makes it easy to disassemble the upper barrel parts and change the operation pipe under full operating pressure.
Optimal sealing
The valve cone of all AVK above-ground hydrants is completely vulcanized with polyurethane (PUR). The high quality of this elastomer ensures an optimal sealing due to its unique memory effect.
Protected signal colour
AVK above-ground hydrants are as standard coated with epoxy resin powder according to GSK guidelines, and due to an additional UV resistant layer of polyester, you will not lose the important signal colour, even after years.
The standard colour of AVK above-ground hydrants is RAL 3000 red. We can also meet your individual colour requirements if e.g. the hydrant is to indicate the type of supply line. For contact with aggressive media such as road salt, the hydrants are available with external enamel (blue or red) for additional robustness.
