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.
NovoCon ChangeOver6:
The NovoCon® S bus actuator controls the flow and the 6-port diverting valve with actuator, switches between heating and cooling, characterized by that:
- There is only one single plug-in cable, with bus connection and power supply to the NovoCon® S actuator. One plug-in cable between the 6-port actuator NovoCon® ChangeOver6 and the NovoCon® S actuator, which includes a 0-10V control signal, feedback signal and power connection.
- The NovoCon® S PIBCV actuator detects by means of comparing 0–10 V control & feedback signal if 6-port actuator is in manual operation or if the valve is blocked (feedback signal does not follow control signal).
- 6-port actuator is in maintenance mode able to fully close the valve to prevent any leakage.
