Description
DSF 4 way reversing vavle 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-pumps systems with the capacity from 0.75PH to 15PH, they are suitable for most
refrigerants such as R22,R134a,R407c and R410a.
