DSF 4-way Reversing Valve is the component to provide heating and cooling from the system to the conditioned space by reversing the flowing direction of refrigerant, which is used at room air conditioners, packaged and central air conditioners. Our reversing valves are designed for heat-pump systems with the capacity from 0.75pH to 12pH; They are suitable for most refrigerants such as R22. R407C, and R410A.
