Caution
The VFW41..U butterfly valves require no maintenance.
WARNING
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 pipe work
- 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 correctly mounted actuator.
