Valve
A device used in HVAC systems to control the flow of fluids (such as refrigerants, water, or gas) within the system. Valves can regulate, start, or stop fluid movement, ensuring that heating, cooling, or ventilating processes function efficiently. They come in various types, such as thermostatic expansion valves, solenoid valves, or ball valves, each serving specific roles in different HVAC components.
