Butterfly valves designed in intermediate flange design, for mounting into gas
trains
Valve either metallically tight or swing thru
DN32...DN200
Effective rotation angle 5…85°
Suitable for gases in the I…III range, air and flue gas up to 180°C
Including coupling for D-shaft Ø 10 mm and ASK33.1 mounting plate
The option is available to install the butterfly valve in the next nominal size
up to ensure it is positioned more securely
Installation in ISO 7005 and ANSI flange connections
The VKF10/VKF11 and this data sheet are intended for original equipment
manufacturers (OEMs) using the VKF10/VKF11 in or on their products.

To avoid personal injury or damage to property or the environment, the following
warning notes must be observed.
Interventions and changes are strictly forbidden.
All activities (mounting, installation, service work, etc.) must be performed by
qualified staff
These valves must not be put back into operation following impact or shock; even if
they do not exhibit any visible damage, their safety functions may be impaired
Ensure that the relevant national safety regulations are complied with
Mounting between counter-flanges conforming to ISO 7005-2 and ANSI
Butterfly valve and actuator can be assembled directly on site with ease
No special tools or adjustment required
The butterfly valve can accommodate flow in either direction
Use flange gaskets that are suitable for the type of gas
The butterfly valve may only be put into operation if the actuator is correctly fitted
The direction of rotation when opening the damper should be clockwise (looking
towards the front face of the axle)
Ensure the actuators being combined rotate in the correct direction: Direction of
rotation ‘counterclockwise’ (12:00 09:00) looking towards the front face of the
actuator axles
Disk turns in clockwise direction Flow increases
Disk turns in counterclockwise direction Flow decreases

Mechanical design
VKF10 butterfly valve
The valve disk and shaft are made of stainless steel.
The valve disk does not close against an end stop.
After mounting the actuator, the position indicator and valve disk are both at 5° so that
the effective setting range can be used.
VKF11 butterfly valve
The valve disk and shaft are made of stainless steel.
The valve disk closes against an end stop (approx. 5° position).
