Commissioning
Commission the valve only if the manual knob or actuator have been mounted
correctly.
The straight-through control path A → AB can be opened either electrically via the
actuator, or by adjustment with the manual button. In the case of 3-port valves, this
throttles or closes bypass B.
Maintenance
V..P47..(S) valves require no maintenance.
When doing service work on the valve / actuator:
• Deactivate the pump and turn off the power supply
• Close the shutoff 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.
