The 4-way Reversing Valve is the key component to provide Heating and
Cooling from the system to the air conditioned space by reversing the
flow direction of refrigerant.
It is used at room air conditioners, packaged and central air conditioners.
The reversing Valves are designed for Heat Pump Systems with capacity from 3kW to 580kW.
They are suitable for most refrigerants as R407C - R410A - R134A.
