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.

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.

AVK dry or wet barrel fire hydrants meet or exceedAWWA C-502 and are all UL/ULC listed and FM

approved. Both types of fire hydrants are designed

for high performance, easy repair and minimum

end user costs for labor and inventory.

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
