Commissioning notes
Commission the valve only if the manual knob or actuator has been mounted
correctly.
The straight-through path A  AB can be opened electrically via the actuator, or
manually. With 3-port valves, this throttles or closes T-bypass B.
Manually, path A
 AB can only be opened to 70 % (T-bypass closes to 30 %).
The valves are closed by a return spring.
Maintenance
V..P45..S valves require no maintenance.
When doing service work on the valve / actuator:
 Deactivate the pump and turn off the power supply
 Close the shuttoff valves
 Fully reduce the pressure in the piping system and allow pipes to completely cool
down
If necessary, disconnect the electrical wires.
Before putting the valve into operation again, make certain the manual knob or the
actuator is correctly fitted.
The stem sealing gland cannot be exchanged. In the case of leakage, the entire valve
must be replaced. Contact your local office or branch.
Disposal
Before disposal the valve must be dismantled and separated into its various constituent

from an ecological point of view.
Current local legislation must be observed.
