Notes
NOTICE
Note the following when servicing a ball valve/rotary actuator:
● Switch off both pump and operating voltage.
● Close shutoff valves.
● Release pressure in the pipes and allow them to cool down completely.
● Disconnect electrical connections from the terminals as needed.
● The rotary actuator must be properly installed prior to recommissioning the ball valve.
● Ensure that there is no cavitation
● Install filter to increase functional security
Technical design/mechanical design
The Siemens 6-port control ball valve has an internal pressure equalization function that
ensures the safe operation of heated and chilled ceilings in a closed valve state (45°
position) Changes to media temperature in the heated and chilled ceiling can result in over
or under pressure in a closed state and may, under certain circumstances even damage part
of the heated and chilled ceiling.
The safety function only acts in the closed valve position (45°). The heating and cooling
circuits are safely separated while operating.
Safety
CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
● Observe national provisions and comply with the appropriate safety regulations.
NOTICE
Use of rotary actuator
Commission the 6-port control ball valve only after it is correctly coupled with the rotary
actuator.
