The invisible infrastructure that creates comfortable and productive indoor environments in buildings and industrial facilities, HVAC(Heating, Ventilation and Air Conditionaing) systems rely on the precise and efficient control of air and fluid flow. Valves, often working silently behind the scenes, are essential components in managing these complex networks, contributing significantly to energy efficiency, occupant comfort, and the overall functionality of our built spaces. In HVAC systems, ball valves provide on/off control, butterfly valves regulate flow in larger systems, globe valves offer precise throttling, check valves prevent backflow, and strainers protect system components from debris. Safety valves are used on boilers and pressurized vessels to release excess pressure.
