AVK is a leading supplier of hydrants and fittings for water supply and fire protection, and we have a long tradition of producing high-quality hydrants, both inhouse and through acquired companies such as Mittelmann Armaturen in Germany and SMHM in France. Our development and production of hydrants benefit from the many years of experience, and the development process has always been focusing on the needs of our customers and the increasing market demands.
Our hydrants are manufactured to all European standards. We turn global feedback and ideas into new constructions, and all hydrants are tested together with our end customers, enabling us to offer the best solutions for all applications.
Our product range consists of a variety of UL/FM approved hydrants, above-ground hydrants and underground hydrants.
UL listed and FM approved hydrants
We always aim at the highest quality, and most of our products for fire protection applications are approved according to both UL and FM. This includes our dry and wet barrel hydrants.
Dry barrel fire hydrants are primarily designed for areas with frost, whereas wet barrel fire hydrants mainly are designed for non-frost areas. AVK dry barrel and wet barrel hydrants are rated for high working pressure and designed for easy maintenance and repair, and they meet or exceed AWWA requirements.

Above-ground hydrants
AVK Armaturen in Germany has a state-of-the-art assembly and test station for above-ground hydrants and hydrants with long pipe cover. After assembly, pressure tests are carried out at this station. As an additional setup is thus not needed, this reduces the time for overall assembly.
The above-ground hydrants offer a high level of safety due to a predetermined breaking point, protected signal colouring, easy maintenance and optimal sealing.
Our standard range includes among other variants hydrants with manual or automatic drainage and with single shut-off or additional ball shut-off.

Underground hydrants
AVK underground hydrants require only a minimum of maintenance. They have superior corrosion protection, pressurized water protection, protected threaded connections, automatic drainage, ergonomic handling and optimal sealing.
Our range of underground hydrants offers single shut-off hydrants with one-piece housing, double shut-off hydrants with two-piece housing, free flow hydrants and hydrants with backflow protection.

Hydrants with corrosion protection in highest quality
AVK hydrants are coated with epoxy resin powder in compliance with DIN 3476 part 1 and EN 14901, and are GSK approved. Each batch of epoxy coated components is controlled to ensure a layer thickness of minimum 250 μm, a pore-free surface, high impact resistance and adequate curing. In addition to our own tests, the independent GSK authorities control the adhesion and cathodic disbonding of the epoxy coating according to their guidelines.
In 2017, the AVK Group took over EMK‘s enamel facilities, and we now have in-house capacity to produce enamelled hydrants of our well-known high quality. The enamel is applied to the surface of the products and then burned at high temperatures in the enamel furnace.
