Commissioning notes
The valves must be commissioned with the actuator correctly fitted. Strong
pressure impacts can damage closed Combi valves.
The Combi valves have to be open when flushing or pressure testing the
system. Strong pressure impacts can damage closed Combi valves.
Differential pressure Δp
max
across the valve’s control path is not allowed to
exceed 600 kPa.
Only possible with mounted actuator.
Maintenance notes
The VPF43.. Combi valves are maintenance-free.
When performing service work on the valve or actuator:
Switch off the pump and disconnect power supply.
Close the shut-off valves in the piping network.
Fully reduce pressure in the piping network and allow the pipes to cool down
completely.
Remove the electrical connections only if necessary.
The stem sealing gland cannot be exchanged. In case of leakage the whole valve
must be replaced.
Do not dispose of the device as household waste.
Special handling of individual components may be mandated by law or
make ecological sense.
Observe all local and currently applicable laws and regulations.
