Engineering notes
Single flange mounting is possible: DN 40…250: 300 kPa
DN 300…600: 200 kPa
The VKF46.. butterfly valves can accommodate flow in either direction.
To avoid pressure shocks on the butterfly valve, the VKF46.. must be driven to its fully
open position (either manually or via positioning signal Y1) prior to activating the
pump(s).
Mounting notes
The Mounting Instructions 4 319 0198 0 are enclosed in the product packaging.
VKF46.. butterfly valves can be mounted in PN 6, PN 10, PN 16 applications.
Use VKF46.450…600 in PN 16 applications only!
Do not use additional flange sealings.

Maintenance
The VKF46.. butterfly valves require no maintenance.
Before performing any service works on the valve, actuator or mounting kit:
∂ Switch off the pump and power supply
∂ Close the main shut-off valves in the pipework
∂ Release pressure in the pipes and allow them to cool down completely
If necessary, disconnect electrical connections from terminals.
The valve must be re-commissioned only with the manual adjuster or the actuator
correctly assembled.
