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 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. On the Lug type and the double flanged type the seat is vulcanized onto the body.

General overview

Chemical

Pulp and paper

Mining and power

HVAC industries

Butterfly valves for high performance applications are found in industries like:

Square stem - angled at 45°

Stainless steel disc ensures blow-out proof stem.

V-ring provides a weather seal.

PTFE bearing ensures perfect turning and centric positioning of the stem. The sleeve bearing provides excellent support if actuators are used for automa-tion purposes.

V-ring as secondary sealing ensures that media does not escape to the atmosphere through the stem guide.

Disc with two-piece shaft con-struction 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.

O-ring anti-dust type.

ISO 5211

Multi-standard alignment holes help mount the valves.

Seat vulcanized to a phenol back-up ring which makes seat replacement very easy. The tolerances assure 100% tightness at full differential pressure. The valve is ideal for vacu-um applications and mounting be-tween flanges is easily done.

V-ring provides a secondary sealing, preventing leakage to and from the stem.

Unique seat wave line rubber seat reduces the torque of the valve and extends the life span of the sealing.

ISO 5211 top flange according to valve torque.

Relief track on the ISO top mounting flange.

Seat A unique dynamic wave line rubber seat provides a highly efficient seal.

Reduced torque.

Extended sealing life span.

Making automation a very price competitive.

On the wafer type the seat is vulcanized to a phenolic back-up ring - a re-placeable construction - on the lug type the seat is vulcanized onto the body.

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 Cv 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.

Construction DN40 - DN300 Wafer & lug type



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 anit-dust O-ring.

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 2231 / Type 2241 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 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

Carefully place the butterfly valve between the flanges, with the disc in closed posi-tion.

Check that the flange covers the area of the liner. Afterwards tighten the bolt 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 left, counter clockwise rotation - CCW - can be applied without prob-lems, if consider that the torque in this case will increase.

The best angle for a closed valve is 90° because of the special design of the liner and rounded disk edge.

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 rotate clockwise - CW - in order to have the lowest possible torque - and thus the longest possible life time.
