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.

The 4-way Reversing Valve are used in reversible applications such as heat pumps or reversible air conditioning units and chillers.

The 4-way Reversing 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 triggers the movement of a slide, thus inverting the flow direction of the refrigerant.

The valve is connected to the suction and discharge pipes. The pilot valve ensures a very reliable changeover from cooling to heating mode; the changeover happens instantaneously with a minimum pressure differential. Heating Cycle Cooling Cycle Cooling Cycle The valve design also guarantees a minimum pressure drop and very low risk of leakage.

The models offer a wide range of connection sizes, configurations and capacity for specific applications. The standard models are available
