The air conditioning valve is a key component of the air conditioning system used to control, regulate or block the flow of fluids (such as water, air, and refrigerant). It accurately manages the flow rate, pressure, and direction of the medium by mechanical or electric means to meet the cooling/heating requirements, ensure the safe operation of the system, and improve energy efficiency.
