ChangeOver6 and NovoCon ChangeOver6 - Motorized 6-port Ball Valves

The ChangeOver6 and NovoCon ChangeOver6 are 6-port motorized ball valves that perform a diverting function between two water circuits in a 4-pipe changeover system.

This diverting function allows the cooling and heating capacity of a fan coil unit to be increased for the same compact size compared to a double coil model, where the heating and cooling water circuits each have their own coil.
​​​​​​​
The ChangeOver6 and NovoCon ChangeOver6 are not suitable for flow control. Flow is modulated by the AB-QM pressure independent balancing control valve to avoid overflow and reduced efficiency of the boiler or chiller.
​​​​​​​
Typical applications include radiant ceiling panels supplied by 4 pipes (heating supply and return, and cooling supply and return) and fan coil units with a single coil supplied by 4 pipes (heating supply and return, and cooling supply and return).
