"Optibal W6" six-way valve for seasonal change-over and proportional control.

The six-way ball valve “Optibal W6” is used for the heating or cooling operation of radiant/ chilled beams or fan coils. With its numerous functions, the ball valve allows for a time- and space-saving installation.

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.
