Fire plays a decisive part in our developement ashuman beings. Under control it is invaluable, but
out of control it can be devastating.
Brave firemen risk their lives to extinguish fires. They rely fully on
their equipment to function perfectly when needed. Therefore it
is crucial that the products installed are highly reliable, are easy
to maintain and last a lifetime. AVK is a leading suppliers of
high quality hydrants and valves for fire fighting and sprinkler
systems. Our unique design and wide product range is based
on the needs of customers worldwide. We offer a wide range of
high quality valves and hydrants which, along with a series of
accessories, build the optimum solution.
The complete fire fighting package complies with international
standards and consists of hydrants, NRS post indicator valves,
hand wheel operated OS&Y gate valves, post and wall indicators,
all UL/ULC listed and FM approved. Furthermore AVK holds VDS
approval for NRS hand wheel operated gate valves.

Dry bar re l hydrants
Ser ies 27 and Ser ies 24
Series 27/00 dry barrel fire hydrant is primarilydesigned for frost areas, where the water main is
located below ground frost zone.
The series 27/00 dry barrel 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. These impurities could lead to dama-
ge of the main valve disk. After turning the operation key 2 to 3
times the drain will stop flushing and the barrel will be filled with
water, which will flow directly into the hoses and pumper hose
or whatever is connected. Furthermore when the hydrant is
closed after service the barrel will drain the water through the
drain holes in the base. Therefore it is important to make sure
that the base is surrounded by gravel allowing the hydrant to
drain and flush without washing off the soil. If not, this could
result in undermining of the pavement.
Series 24 wet barrel fire hydrant is designed for
non frost areas.
The series 24 wet barrel hydrant is designed with the shut-off
device directly at the outflow nozzle for hose or pumper connec-
tion. This means that the hydrant is constantly filled with water
and thus under pressure.
The hydrant is mounted directly on the water main, giving full
water pressure instantaniously when needed.
Only after 1/8turns on the stem the water starts to flow, and
after 12 turns the full flow capacity can be held against the fire.
The hydrant is not for use where the temperature may come
below 0C, due to the risk of frost bursting.
In order to service and maintain the hydrant, we
recommend installing an isolating gate valve on the
upstream side.

Series 84/60
The series 84/60 monitor hydrant is particularly made for fire
fighting in the chemical and petro-chemical industry, for refine-
ries, tank farms, and airports where large quantities of explosive,
flammable liquids are handled and thereby constitute a risk.
The hydrant is supplied with two 2 1/2 hose nozzles and one
4 pumper nozzle. The nozzles are supplied with
the patented Easy-open system that makes
an easy and fast opening of
the nozzle possible - even at
high pressure.
Horizontally the hydrant turns 360
continuously variable, and vertically the
monitor can be adjusted from 45 to 70
- also continuously variable.
The Monitors HH365 and HH366 are
both PN 16. They have a capacity of
2000 respectively 3000 litres/hour and
are suitable for both water and foam.
The capacity of the spray nozzle is adjustable from
1100 to 3000 litres/hour at 8 bar. Furthermore, the
monitor can be supplied with a self-priming foam pipe,
and the foam blend can be continuously variable adjusted from
2-6%.
Maintenance/repair of the hydrant can be made on location.
The well-known ball shut-off principal allows replacement of the
inner parts of the hydrant under full pressure without using spe-
cial tools. In this way, the hydrant does not have to be isolated
from the ring main. The spindle rod is made of stainless steel, and
the plug is made of polyamide GTW synthetic elastomer.

Post or wall indicators are mounted end to endwith the extension spindel connecting the valve.
It is mounted in places where direct access is
impossible. It could be gate valves mounted on
a water ring main in a factory area, such as oil
refineries, chemical plants or airports.
The post indicator indicates if the mating valve is in open or
closed position. According to government regulations it must
be easy for firemen to see if the valve is open or closed, even at
a long distance. The post indicator signs OPEN AND SHUT are
mounted on the target according to clear locations and accordingto valve size.

The post indicator valves are used for under-ground installation in fire fighting systems. The
post indicator flange is incorporated in the top
gland giving a compact design.
The post indicator indicates the position of the wedge, whether
it is open or closed.
The basic valve construction is, like valves for water supply,
characterized by a fully rubber coated wedge, full and straight
bore, low torque operation and O-ring stem seals exchangeable
under pressure.
The valves are available with flanges, mechanical joints or push-on
joint ends in DN 100-300 (4" - 12").

A published test from
City of Roseville, US, has
proved that impurities up
to 8.7 mm can be
handled by a DN 150 mm
valve without any problems.
The same test has also
proved that the unique
AVK rubber quality EDK
70 is the only rubber
quality which instantly
returns to the original
shape when the valve is
opened again.

Series 06/35 - The light weight flanged gate valve isvery suitable for use in fire fighting systems as an
isolating gate valve for maintenance purpose.
The pin indicator indicates the wedge position. Micro switches
for remote indication of the wedge in open or closed position
are available as an optional extra.
The basic valve construction is, like valves for water supply,
characterized by a fully rubber coated wedge, full and straight
bore and 3 independant stem seals.

AVK resilient seated gate valves are designed with
a fully vulcanised rubber wedge - internally and
externally.
With this design no iron parts are exposed to the medium and
the excellent rubber vulcanisation prevents creeping corrosion
underneath the rubber. The rubber is vulcanized onto the wedge
by AVK GUMMI A/S, one of Europe's leading manufacturers of
high technology moulded rubber components.
The high quality of AVK rubber is characterized by:
Smell and taste response characteristics highly suitable for
the food industry
Very low deformation ensuring optimum sealing
High impact resistance preventing corrosion
Low friction ensuring low closing torques
EPDM rubber for water supply, NBR rubber for gas supply
