In a 4-pipe ChangeOver6 system switching flow between heating and cooling circuits is done with a 6-port motorized ball valve, connected directly to digital PIBCV actuator.
Flow control for heating and cooling circuit is performed by a separate pressure independent control valve and modulating actuator. 1)
6-port ball valve:
6-port ball valve actuator:
1) A separate tender text is available for the Danfoss AB-QM pressure independent balancing & control valve and NovoCon fieldbus actuator.
The Danfoss ChangeOver6 is a 6-port motorized ball valve that switches flow between a heating and cooling water circuit in a 4-pipe system and eliminates cross-flow. A single digital signal switches between heating and cooling, and flow control must be performed by a separate pressure independent control valve that can modulate flow rates to suit the heating and cooling circuits.
A separate tender text is available for the Danfoss AB-QM pressure independent balancing & control valve and the AME110NL 0-10V geared actuator and the NovoCon® S BACnet and ModBus geared actuator.
Branch should be balanced with a differential pressure controller for dynamic hydronic balance, with following characteristics:
AB-PM DN 40-100 is a combined differential pressure controller for dynamic hydronic balance.
The pressure independent balancing and control valve which means that the control characteristic is independent from the available pressure. The precise flow control performance of the AB-QM with a Danfoss actuator provides increased comfort and superior Total Cost of Ownership. The AB-QM ensures and control the required flow on every terminal unit and maintains Hydronic balance in the system.AB-QM has following features:
Available in the range from DN 10 – 250 from one supplier.
a. Pressure class: PN 16
b. Temperature range: 0 … +120 °C
c. Connection size: DN 15-50

e. Δp setting range: 5-25 kPa, 20-60 kPa
f. Max differential pressure across valve:1.5 bar
g. Installation: differential pressure controller should be mounted on return pipe with connection via impulse tube to supply pipe.
Domestic hot water installations should be balanced with thermostatic balancing valve for a constant water temperature in the system with following characteristics:
Product is a manual valve for balancing flow in heating, cooling and domestic hot water systems. Branch should be balanced with a manual pre-setting valve with test plugs for commissioning or/and flow verification, with following characteristics:
Product is a manual presetting valve for balancing the flow in heating and cooling installations.
