Construction
Stainless steel disc ensures blow-out proof
stem
V-ring provides a weather seal
O-ring as secondary seal-ing ensures that media does not escape to the
atmosphere through the stem guide
Disc with two-piece shaft construction enhances the flow capacity of the valve.
The shape of the disc provides lower torque and
prolongs the life span of the valve
PTFE/graphite bearing ensures perfect turning
and centric positioning of the stem. The bearing is
placed inside the disc
Seat vulcanized to a phenol back-up ring which
makes seat replacement very easy. The tolerances
assure 100% tightness at full differential pres-
sure. The valve is ideal for vacuum applications and
mounting between flanges is easily done
Square stem - angled at 45°. Material is AISI 420 or AISI 431 to insure high torque transmission with-out damage. Smooth finish surface
PTFE bearing ensures perfect turning and centric positioning of the stem. The sleeve bearing pro-vides excellent support if actuators are used for automation purposes
High quality GGG40 steel body with standard ISO 5211 mounting flange.
Body is coated according to ISO 12944 C3 industrial standard with 3 layer Epoxy/Epoxy/PUR 160µ
Both Wafer and LUG has fully changeable liner con-struction.
LUG model has a specialy designed grove to insure uni-directional “end of line” installation with full differ-ential pressure
O-ring anti-dust type
Bottom plug ensures blow-out proof design and acts as a weather seal
Bottom stem in AISI 420 or AISI 431 with smooth sur-face finish
Unique seat wave line rubber seat reduces the torque of the valve and extends the life span of
the sealing. DN40-DN300

Extended life spanThis butterfly valve has a unique wave line rubber seat and a special disc shape, enhancing the life span of the valve and sealing.
Reduced torqueDue to the unique wave line rubber-seat and disc shape, the butterfly valve has a low breakaway torque.
One of a kind It is the only butterfly valve in the world constructed with a bushing inside the disc - resulting in lower torque, lower friction, 100% tight shut-off function and a very long service.
Seat constructionOn the Wafer type the seat is vulcanized onto a phenol back-up ring. The seat is replaceable.

Body GGG40 is standard - 3 layer coating EPOXY/EPOXY/PUR, 160 µ.
Types: Wafer and LUG
Wafer has multi-standard alignment holes suitable for mounting flanges:DN40 - DN300 wafer type: EN1092 PN10, PN16 - ANSI150 - BS10 TABLE D, TABLE E, JIS 10K, 16K.DN350 - DN600 wafer type: EN1092 PN10, PN16 - ANSI150 - BS10 TABLE D.
LUG has fixed threaded holes suitable for specific flanges:DN40 - DN150 lug type: EN1092 PN10 or PN16 or ANSI150.DN200 - DN600 lug type: EN1092 PN10 or PN 16 or ANSI150.Mounting bolts lug: PN = Metric and ANSI = UNC
ISO 5211 top flange according to valve torque.
Relief track on the ISO top mounting flange.
SeatA unique dynamic wave line rubber seat provides a highly efficient seal.
Reduced torque making automation very price competitive.
Extended sealing life span.
On the Wafer and Lug type the seat is vulcanized to a phenolic back-up ring - a replaceable construction.
Simple seat replacement.
100% tightness at full differential pressure (PN16 = 16 bar from DN40 - DN150, PN10 = 10 bar from DN200 - DN600).
Ideal for full vacuum applications.
Trouble-free mounting between flanges.
DiscDisc with two-piece shaft construction which enhances the Kv-value of the valve and reduces turbulence.
The shape and finishing of the edge of the disc, provides the lowest possible operating torque with bubble-tight shut off, even at maximum operating pres-sure, thus extending the life span of the valve.

Shaft / bearingsSquare stem.
PTFE bearing ensures perfect turning and centric positioning of the stem.
The sleeve bearing provides excellent support, where actuators are used for automation purposes.
Unique bottom bearingThe bottom PTFE/Graphite bearing is one of a kind - it is placed inside the disc, where it is actually needed.
Usually there would be a bearing in the bottom of the body - which means a rotating shaft that transmits the forces put onto the disc down to the bearing.
The result is a displacement of the forces and this is prevented by the unique bottom bearing - giving the valve a longer and trouble-free life span.
Long shafts for transmitting force are more vulnerable to excessive torsion than short shafts.
V-type ring and end cover The V-ring provides a secondary seal which prevents leakage to the stem.
The V-ring also provides a weather seal.
The end cover is sealed at the bottom with a threaded plug.
The end cover has an anti-dust O-ring.

*Valve is completely closed and opens 2 times a day minimum.** Valve is completely closed and opens only one time per week or longer. Having a long period without maneuvering the valve, will increase the breakaway torque.NB: Please maneuver the DVC butterfly valve at least one time per month to avoid deformation of the rubber seat.

Approvals LINER INFO
Determining the size of butterfly valves for control purposes should not be done on the basis of the nominal diam-eter of the pipe but should be calculated on the basis of the operating characteristics in order to attain the correct control characteristics.
Butterfly valves Type 2232 / Type 2242 from Dansk Ventil Center are designed with approximately equal percentage characteristics over an opening angle of 65°.
You only need to consider the opening angle when determining the size of control valves. When determining the valve nominal diameter calculate the Kv value from the below formula:

Rubber liners (NBR, EPDM-HT and FPM):
Rubber will over time loose flexibility and compression set. The higher the temperature rubber is installed in, the shorter the expected lifespan is. Our values for temperature is given to the best of our knowledge, and we advice that valves are tested for lifespan if installation is running near the given temperature limit. If in doubt, please consult us.

Check that the specifications on the identification plate meet the require-ments regarding pressure, temperature and media.
The piping must have a straight line and the flanges have to be parallel. Furthermore there must be a distance between the flanges, corresponding to the face-to-face dimensions of the butterfly valve.
The butterfly valve can be mounted in any direction. However if there are a lot of dirt particles on the bottom of the pipe, it will be suitable to mount the stem of the butterfly valve horizontally. This will protect the pivot point of the disc.
Before commissioning, the pipe work has to be rinsed out to remove dirt and remnants of welding material, to avoid damage on the liner. During the rinsing procedure, the butterfly valve has to be positioned as open and may not be operated, before the rinsing has been completed.
Welding operations may not be performed nearby the butterfly valve, as welding drops can damage the liner.
Do not use gaskets. The liner works as sealing to the atmosphere.
Where vacuum, high flow rate or water hammering can occur, flanges with-out a loose collar should be used, to obtain the best conditions.
Installation guide forButterfly Valves
Check that the flange covers the area of the liner. Afterwards tighten the bolts on the flange by hand.
Carefully open and close the valve to check that the disc centralizes and the disc does not touch the flange. With the disc in the open position, tighten crosswise with a wrench.
Though the valves are constructed to work as shown on the right, counter clockwise rotation - CCW - they can be reversed without problems. Please consider that the torque in this case will increase.
As the butterfly valves are equipped with the unique wave shaped liner, the operation of the valves, either free stem, handle or gear operated, has to follow the guidelines as shown below.
A small triangular shaped figure is placed on the liner - this triangle indicates which way the disc has to enter the liner.
Generally spoken the disc has to close clockwise - CW - in order to have the lowest possible torque - and thus the longest possible life time.
Installation guide
Turn disc CW towards arrow to close
Turn 90° CW to close
Carefully place the but-terfly valve between the flanges, with the disc in closed position.
