The valve is equipped with flexible spring wings intended to fit in sheet metal fittings.
It is recommended that the valve is mounted in the frame ILVRU. The product will also fit in the
valve frames VRGU, VRGM, VRFU, VRFM and BU GJUT and TCPU GJUT.
The valve body has to cover the brim of the product it is fitted into. Therefor the maximum
diameter of the brim for Ø100 is 133,5 mm, for Ø125 is 152,5 mm and for Ø160 is 187,5 mm.
To mount the valve press the valve’s body into the frame and rotate it clockwise. To demount
the body rotate it clockwise while pulling.
Mounting of valve
Mounting close to
wall or ceiling
Mount the duct system firmly so the
valve can be properly attached to the

When balancing the valve it is important
that the frontplate can be rotated 360°.
If it is impossible to rotate it the front
plate has to be removed before each
adjustment

At Lindab,good thinking is a philosophy that gui-
des us in everything we do. We have made it our
mission to create a healthy indoor climate – and
to simplify the construction of sustainable buil-
dings. We do that by designing innovative pro-
ducts and solutions that are easy to use, as well
as offering efficient availability and logistics. We
are also working on ways to reduce our impact on
our environment and climate. We do that by de-
veloping methods to produce our solutions using
a minimum of energy and natural resources, and
by reducing negative effects on the environment.
We use steel in our products. It’s one of few materi-
als that can be recycled an infinite number of times
without losing any of its properties. That means
less carbon emissions in nature and less energy
wasted.
