4 - way r e v e r s i n g va lv e s s e l e c t i o n
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.

4 - way reversing valves selection
The pilot valve ensures a very reliable changeover from cooling to heating mode; the
changeover happens instantaneously with a minimum pressure differential. The valve
design also guarantees a minimum pressure drop and a very low risk of leakage.
The STF models offer a wide range of connection dimensions, congurations and
capacity for specic applications. The standard STF models are packed as 1 pc. per
box providing increased exibility.
