Good quality Proportional Reversing valve

Reversing valve is a component in a heat pump or air conditioning system that allows the system to switch between heating and cooling modes. It is responsible for reversing the flow of refrigerant in the system, allowing it to absorb heat from the outside air and transfer it to the inside during heating mode, and vice versa during cooling mode. The reversing valve is typically controlled by a solenoid that is activated by the thermostat, which signals the system to switch modes as needed to maintain the desired temperature.
