HVAC valves are critical components used in heating, ventilation, and air conditioning systems to regulate the flow of fluids such as water, steam, and refrigerant. These valves play a vital role in maintaining the desired indoor temperature and pressure by directing, controlling, or shutting off the fluid flow based on system requirements. Whether manually operated or automatically controlled through building management systems, they help ensure precise climate control, system safety, and energy efficiency.

The design and function of HVAC valves vary depending on their purpose. Some are used to modulate flow for temperature control in different zones of a building, while others act as safety devices to release excess pressure or prevent backflow. Their application spans both residential and commercial systems, making them indispensable for maintaining optimal performance and comfort in indoor environments.
