Request Information

Danfoss 4-Way Reversing Valve, STF

The 4 way 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.

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

The valve is connected to the discharge and suction pipes.
