The smart refrigerant valves from Bosch are characterized by low installation space and optimized weight. Refrigerant valves are electronically controlled components that optimally regulate the refrigerant circuits in the vehicle. Refrigerant valves consist of two subsystems: a hydraulic component and an electromechanical drive, the actuator.

Refrigerant expansion valves can be used, for example, to regulate overheating or excessive cooling. Refrigerant switching valves control the refrigerant system by switching areas on or off depending on need, for example, to cool the battery or the cabin. The pressure loss of the refrigerant valves is very low so they are suitable for a highly efficient heat pump application.
