5. Completed Arma-Chek eccentric reducer made of
factory-coated Arma-Chek D sheet material.
VALVE COVERINGS
Insulate the connected pipes to a length of 100 mm and
the valve spindle depending on its length using uncoat-
ed Armafl ex.
1. Determine the dimensions -
diameter of the end disc:
a = diameter of the fl ange + 2 x insulation thickness
height of jacket:
b = from end of screw to end of screw + 5 mm allowan
jacket opening:
c = diameter of the insulatedvalve spindle
end disc opening:
d = diameter of the connected pipes + 2 x ins. thickness
Note:
5 mm must be added to the jacket height deter-
mined. 5 mm must be subtracted from all measur-
ments for openings.
2. Cross-section A-A: Determine the circumference of
the fl ange with a strip of Arma-Chek D.
3. Transfer the measurements determined to the
appropriate pre-coated Arma-Chek sheet.
Install the valve covering and securely bond all areas
where there is a risk of penetration with the appro-
priate Armafl ex adhesive.
For indoor applications
, cover the uncoated insula-
tion on the pipes and the valve spindle with 100 mm
wide Arma-Chek Dself-adhesive tape.
On outdoor applications
, use 100 mm wide strips
of the covering material.
Measure and cut the covering for the valve spindle
as described in the chapter ”Applying covering
material: Valve-Ts / Pipe-Ts“ (see page xx).
