Danfoss Saginomiya 4-way Reversing Valves are used in reversible applications such as heat pumps or reversible air conditioning units and chillers.

The 4-way valve allows an inversion of the refrigeration cycle, changing from cooling mode in summer to heating mode in winter.

They are also used in heat pumps (air cooled) for de-frosting.

The cycle inversion is initiated by a small solenoid pilot valve controlling the movement of a slider, which changes the direction of the refrigerant.
