Extensive range of butterfly valves
AVK was founded in 1969 and in the first years we focused on gate valves. From the 90s we started offering butterfly
valves. AVK became distributor of centric fixed liner butterfly valves from Wouter Witzel, a well-esteemed manufacturer
founded in 1966 in the Netherlands and since 2005 a member of the AVK Group.
The same year AVK introduced a brand new range of double eccentric butterfly valves. DN 1400-2200 were added to the
range a few years ago and are manufactured at Glenfield in the UK, the AVK Group specialist in large diameter valves.
In 2008 AVK acquired World Valve, a small manufacturer strong within customized butterfly valves.
In 2010 InterApp Armaturen Holding AG became member of the AVK Group. InterApp was founded in 1969 and is a
well reputed manufacturer of centric loose liner butterfly valves produced in Spain and Switzerland. Today approx.
3,000 people in the AVK group are doing their utmost to ensure that AVK remains one of the world’s leading valve
manufacturers for water, sewage, gas and fire protection applications.

Internal and external epoxy coating to DIN 30677-2 and GSK guidelines
All castings are blast cleaned according to ISO 12944-4. Any unevenness of the product surface is cleaned to provide
perfect adhesion of the coating. The epoxy is electrostatically applied in a closed booth, where the powder melts and
cures in contact with the preheated component. Thorough control measures ensure optimum corrosion protection. Our
double eccentric butterfly valves from DN 1400 come with a two-pack epoxy, and our centric butterfly valves with loose
liner in DN 450 and above are supplied with a 250 my polyurethane coating.

Excellent ability to regain original shape
AVK GUMMI A/S has a special focus on the
compression set value, meaning the ability to regain
original shape. Even after many years of service
where the rubber has been compressed numerous
times, it will regain its original shape and ensure a
tight sealing. Impurities will not affect the rubber
surface or the tightness of the valve, as the impurities
will be absorbed in the rubber when the valve is in
closed position.
Furthermore, the rubber recipes are composed with
focus on minimising the formation of biofilm to
prevent the rubber from forming breeding ground
for bacteria.
Traceability and durability in focus
The rubber materials for liners and sealings are
developed and manufactured by AVK GUMMI A/S
with the use of highly advanced technologies.
Data is constantly collected throughout the entire
manufacturing process and this secures traceability
of every individual ingredient, each compound, and
the finalised components. A number of tests are
carried out to make sure that the compression set
values, the tensile strength and the resistance to
water treatment chemicals meet the predefined
requirements.

Double eccentr ic but ter f ly valves
for buried service
Tilted and fixated disc extends service life and eases operation
The tension on the disc is released after a few degrees of opening which gives only insignificant wear
of the disc seal. Furthermore, the design minimises the compression of the sealing which ensures
low operating torques. The disc is fixated with two set screws to prevent wear of the keyway and
thus to avoid fluttering caused by flow velocity and play in the key and keyway connection. In larger
dimensions the disc is fixated with two stainless steel drive dowels, with key and keyway as back-up.
The dowels are mounted with press fit leaving no play between disc and shaft.
Double eccentric principleThe shaft is placed offset the centre line in both directions. Eccentricity relates to the centre of the pipeline. Double eccentricity relates to the valve centre (approx. 3-5 mm). The disc swings open/closed like a door.

and disc design
Disc seal optimised for high performance
The disc seal is shaped to secure fixation in correct
position providing a very reliable function. The
excellent rubber quality makes it possible to reduce
the amount of rubber which results in low closing
torques. The EPDM sealing is of course approved by
DVGW, KIWA and WRAS.
The stainless steel retainer ring keeps the disc seal
in place. It is fixed by stainless steel bolts coated
with precoat 80 to prevent loosening. The threaded
bolt holes in the disc are corrosion protected with
O-rings.
Two seat designs
AVK offers double eccentric butterfly valves with
two different seat designs. The integral seat design
has a machined and epoxy coated ductile iron seat
integrated in the body. The stainless steel seat design
has a replaceable seat ring of stainless steel sealed
with an O-ring. For DN 200-600 valves the ring is
pressed into the body, and for larger dimensions the
ring is fixed with bolts sealed with epoxy.
Two disc designs
Two different disc designs - plate design and flow-
through design - are available to meet all market
requirements worldwide.
Flow-through designThis design is less sensitive to cavitation at high flow velocities. The design is available for DN 700-1200 butterfly valves.
10 | Butterfly valves for drinking water
Superiour corrosion protect ion
to the core
Design of ≥DN 700The shaft ends are fully encapsulated in the disc and are fixed with dowels. There are two O-rings on each dowel, which are protected with a stainless steel plate fixed with stainless steel bolts.
Protected shaft end zones secure durability
There are no uncoated ductile iron surfaces exposed to the media. In
DN 200-600 the shaft ends are protected with stainless steel plates
with gaskets. After mounting and successful pressure test, an extra
layer of epoxy coating seals the steel plates. In larger dimensions the
shaft ends are fully encapsulated in the disc and fixed to the disc with
dowels. The low friction PTFE shaft bearings ensure low operating
torques for the complete range.

Replaceable shaft sealing and optional locking
The shaft sealing is replaceable under pressure to
enable easy maintenance. Sealings of EPDM secure
tightness from inside and out, and NBR sealings
protect against impurities from outside.
•DN 200-600: An EPDM O-ring on a stainless steel
ring, a back-up EPDM O-ring in the housing, a flat
EPDM gasket, and an NBR O-ring.
•DN 700-2400: Two EPDM O-rings on each side of
the bronze bushing, and a flat NBR gasket.
We offer an optional locking device which makes it
possible to lock the disc in open/closed position.
In addition to all the design features and benefits, we
have minimised the weight to make handling easier
and to put less strain on the environment.
The valves are bi-directional even though valves
from DN 700 and up are marked with an arrow
indicating the preferred flow direction. The hydraulic
test is always done from both directions according to
EN 1074-1 and 2 / EN 12266.
AVK can offer any type of actuation. Our standard
options are IP67 gearboxes with handwheel for
above ground installation, IP68 gearboxes for buried
service, and ISO-input gearboxes for mounting of
electrical actuators. Furthermore, we offer extension
stems, adaptors and handwheels.
The valves are approved by DVGW, KIWA and WRAS
up to DN 1200. For larger dimensions all components
are approved.

Wouter Witzel EuroValve is one of very few manufacturers of butterfly valves with fixed liner. The rubber
is injection moulded directly on the valve body forming a permanent bond with an optimal rubber
shore hardness. Consequently, there is no risk of deformation or dislocation of the liner making the
valves suitable under vacuum conditions. The disc has a profiled sealing edge which requires minimal
deformation of the liner to achieve a tight sealing. This gives less wear of the liner and low operating
torques. Therefore, the butterfly valves are the ultimate choice for applications with high operation
frequency.
Tightness even after thousands of operation cyclesThe combination of a profiled disc and the unique AVK rubber compound secures a great durability. The rubber compound has an excellent ability to regain shape after compression, and the profiled disc requires minimal deformation of the liner.

Low operating torques enable lower total costs
Wouter Witzel EuroValve butterfly valves are a cost
effective choice, especially when it comes to large
diameter valves with actuators.
The fixed liner combined with the profiled disc and
the shaft bearings result in low operating torques.
This makes it possible to use a smaller actuator, and
since the cost of the valve is insignificant compared
to the cost of the actuator, there is no sound reason
for compromising on the valve quality.
Streamlined disc results in low energy costs
The streamlined disc shape results in low flow
resistance when the valve is open. Therefore, the
valves will not cause any turbulence, pressure drops
or valve vibration, and will reduce energy costs for
the user. The saving of energy costs may be several
times the initial cost of the valve.
Valve design based on in-depth knowledge
The disc is fixed to the shaft with a conical pin. Both
shafts are provided with self-lubricating bearings of
PTFE coated steel which contribute to low operating
torques. At the valve top a bronze bushing with
O-ring seals against impurities from outside.
The butterfly valves are approved by DVGW, KIWA,
WRAS and SVGW.

faces and reinforced seating area •Low friction PTFE coated bearings•POM bearings and EPDM O-ring
Wide range of loose liner butterfly valves
The loose liner design also has advantages over the fixed liner design. The cash benefit is the low
purchase price, especially in the smaller dimensions. Additionally, the loose liner makes it possible
to apply coating internally and externally and secure a strong corrosion protection around the liner.
AVK offers two ranges; Series 76 is our basic range available as wafer and lug in DN 50-200 with
lever and DN 250-300 with wormgear. Series 820 is our new full range from InterApp available as
wafer, lug and U-section in DN 25-1600 with any type of actuation.
