Six-way ball valve Optibal W6
PN 16, DN 15, External thread with Eurocone, Kvs: 3.2


Six-way ball valve for combined heating and cooling systems. For switching between heating and cooling mode in four-pipe systems, for example heating/cooling ceilings or fan coil units. 
The Optibal W6 consists of two three-way ball valves arranged one above the other, which are connected to each other via a common rotary axis. It takes over the tasks of up to four straight valves. This way, not only the space required but also the material and installation costs can be reduced. 
In the rotation angle between heating and cooling position there is a closing zone to ensure complete separation of the heating and cooling circuits. Markings at the end of the spindle make the position visible even when the actuator is removed.
Mounting: M5 threaded hole on the underside of the fitting.

Nominal size: DN 15
Connection size: G ¾ external thread with Eurocone according to EN 16313, centre distance 50 mm

Technical data:
- Operating temperature : 0 °C to 90 °C
- Pressure rating: PN 16
- Differential pressure: max. 2 bar
- Flow characteristic line: linear

Kvs values:
- Heating mode: 3.2
- Cooling mode: 3.2
Reduced Kvs values with orifices, item no. 1132020 (accessory)
- Heating mode: optionally 2.5 / 1.6 / 1.0 / 0.63 / 0.4 or 0.25
- Cooling mode: optionally 2.5 / 1.6 / 1.0 / 0.63 / 0.4 or 0.25
Kvs orifices can only be installed in the correct position and thus ensure a quasi-linear characteristic line.
