Six-way ball valve “Optibal W6” rotary actuator “Aktor R ST L”

“Optibal W6” Six-way ball valve for heating/cooling operation control

The six-way ball valve with the rotary actuator “Aktor R ST L” is used for heating and cooling operation of radiant/chilled ceilings or fan coils. Compared to standard installations, the ball valve allows for a space saving installation. Advantageous application options are possible.

Room heating and cooling are combined in more and more buildings. A four-pipe system for room temperature control which allows for zone-wise switching between heating and cooling operation is installed in these buildings. In classic four-pipe systems, many individual control components are required for switching between heating and cooling operation and for room temperature control.
The Oventrop six-way ball valve “Optibal W6” is equipped with the rotary actuator “Aktor R ST L” and is connected to the centralised building control system. The four valves with actuator in a four-pipe system can be replaced by this combination.

The six-way ball valve is made of dezincification resistant brass.

Manual hydronic balancing can be carried out via kvs orifices. They allow for a volume flow limitation and a linear opening characteristic line of the six-way ball valve.

When combined with thermostatic valves “AQ” or pressure independent control valves “Cocon QTZ”, the six-way ball valve/actuator combination allows for automatic hydronic balancing. In case of larger volume flows, the pressure independent control valves “Cocon QTZ” can be used instead of the thermostatic valves “AQ”.

The Oventrop six-way ball valve “Optibal W6” received the “German Design Award 2019” in the category “Special Mention” label.
