The butterfly valves are designed to adjust volumes
of gas, cold and hot air and flue gas on gas and air
appliances and flue gas lines. They are designed for
a control ratio of up to 10:1.
Actuator IC and butterfly valveBV.. (IB..) are suitable
for regulating flow rates for modulating-controlled or
stage-controlled combustion processes.
This function is only guaranteed when used within the
specified limits– see page7 (Technical data). Any
other use is considered as non-compliant.

closing function is used for controlled shut-down
or for intermittent switching of the burner, this will
reduce the service life of the butterfly valve.

Installation
CAUTION
Please observe the following to ensure that no
damage occurs:
– Dropping the device can cause permanent dam-
age. In this event, replace the entire device and
associated modules before use.
– Avoid pressure surges and temperature shocks.
– Sealing material and dirt, e.g. thread cuttings,
must not be allowed to get into the unit.
– Do not store or install the unit in the open air.
– Flange sealing surfaces must not be damaged
by mechanical or other effects.
– If the actuator is retrofitted, the torque, direc-
tion of rotation and adjustment angles must be
adjusted to the butterfly valve.
▷A filter must be installed upstream of every sys-
tem.
▷The length of the inlet and outlet section should
be 2xDN.
▷
The butterfly valve is intended to be installed
in-between two flanges.
▷Installation in the vertical or horizontal position,
not upside down. BVHR/IBHR: always position
the actuator to the side of the pipe.
▷ We recommend installing the butterfly valve in
the vertical position with the direction of flow from
bottom to top in order to prevent condensation
and to prevent dirt from accumulating on the
stop bar in the case of butterfly valves with stop
bar (BVH..A).
Hot air as a medium
▷
If you are using an insulated pipeline ensure that
there is sufficient installation space to access the
screw connectors near the valve. Do not insulate
the butterfly valve with thermal insulation.
▷ For a better dissipation of heat, turn the but-
terfly valve when installing so that the actuator
is positioned to the side of the pipe.
▷Use heat deflectors for a medium temperature
of >250°C, see accessories.
▷Check the temperature resistance of the seals.

Mounting the actuator to BVA, BVG
▷If the butterfly valve is to be mounted to an ac-
tuator other than an IC 20/IC 40, an adapter set
will be available, see accessories.
▷For further information on assembly of butterfly
valve BVA, BVG with actuator IC 30/IC 50, see
accessories or Actuator IC 30/IC 50 operating
instructions, see www.docuthek.com →Thermal
Solutions →Products →03 Valves and butterfly
valves.
Mounting the actuator IC0/IC40 to BVx
▷
If the actuator and butterfly valve are pre-
assembled (IB..), the fastening set will already be
fitted. If the actuator is retrofitted, the fastening
set is delivered enclosed as an additional item,
see accessories.
▷ The actuator IC 20, IC 40 may be installed rotated
by 180° on all butterfly valves.
CAUTION
– If the actuator is to be rotated by 180° following
assembly to the butterfly valve, the actuator
must be detached from the butterfly valve. Only
turn the actuator. Otherwise, a change in the
direction of rotation of the valve can lead to
damage being caused to the mechanical and
electronic components.

Maintenance
The butterfly valves BVG, BVGF, BVA, BVAF, BVH,
BVHR and BVHS require little servicing.
We recommend a function check once a year.
BVG, BVGF: check for external tightness once a
year. If operated with biogas, a tightness test and
function check must be carried out every six months.
