Dry barrel fire hydrants
Dry barrel fire hydrants are primarily designed for areas with frost, where the water main is located below the ground frost zone. AVK dry barrel fire hydrants are UL listed and FM approved for fire protection applications and they meet or exceed AWWA C-502. They are rated for a working pressure of 17.2 bar (250 PSI), and they are designed for high performance, easy repair and minimum end user costs for labor and inventory.
High performance and easy repair
AVK dry barrel fire hydrants are designed with a breakable flange and a stem rod coupling which prevent leaking and enable easy repair at traffic knock down. The fire hydrant’s main valve has a ductile iron core which is fully encapsulated in EPDM rubber. The nozzle section can be rotated 360 degrees. The upper section of the fire hydrant is repairable under pressure.
The dry barrel fire hydrant has two drain outlets located just above the water main level. The main valve disc is designed with the purpose of flushing the drain channels for soil and other impurities during opening, as these impurities could lead to damage of the main valve disc. Furthermore, the barrel will drain the water through the drain holes in the base when the fire hydrant is closed after service.

Wet barrel fire hydrants
Wet barrel fire hydrants are designed for non-frost areas. AVK wet barrel fire hydrants are easy to maintain and are rated for a working pressure of 13.7 bar (200 PSI). They are UL listed and FM approved, and meet or exceed the requirements of AWWA C503.
AVK's wet barrel fire hydrant is designed with the shut-off device directly at the outflow nozzle for hose or pumper connection. This means that the fire hydrant is constantly filled with water and thus under pressure. The fire hydrant is mounted directly on the water main, giving full water pressure instantaneously when needed. AVK wet barrel fire hydrants are available with a breakable flange to enable easy repair at traffic knock down.
