Reverseringsventiler

Reverseringsventiler, also known as reversing valves or four-way valves, are a type of valve used to change the direction of fluid flow in a system. They are most commonly found in refrigeration and air conditioning systems, where they are used to switch between the heating and cooling modes. In these systems, the reversing valve redirects the flow of refrigerant to either the indoor or outdoor coil, allowing for the transfer of heat in either direction. This is what enables a heat pump to provide both heating and cooling.

The operation of a reversing valve typically involves a sliding spool or a rotating disc that, when actuated, redirects the flow paths within the valve body. This change in flow path alters the direction of the refrigerant. The actuation can be achieved electrically, often through a solenoid, or mechanically. The primary function is to control the direction of the working fluid to achieve different operational modes within a thermodynamic system. Beyond HVAC, reversing valves can be found in other hydraulic or pneumatic systems where directional control is essential, such as in some industrial machinery. The design and size of reversing valves vary greatly depending on the specific application and the volume of fluid they are intended to control.
