4-way valve De Dietrich 7652681

The 4-way valve is a directional control component used in heating systems to reverse refrigerant flow, enabling both heating and cooling modes in heat pumps. It directs the flow of gas between the compressor, condenser, and evaporator. In boiler and burner applications, it is essential for efficient heat transfer and system versatility. This valve is a critical spare part for maintaining multi-functional heating equipment. When replacing a worn unit, a new 4-way valve ensures proper cycle switching and system performance.
