Hvac Valves Types, HVAC (Heating, Ventilation, and Air Conditioning) systems employ various types of valves to control the flow of fluids or gases within the system. Some common types include ball valves, which offer quick shut-off capabilities and minimal pressure drop. Butterfly valves are compact and lightweight, suitable for large flow applications. Globe valves provide precise flow control and are often used in hydronic systems. Gate valves offer excellent sealing capabilities but are slower to operate. Additionally, check valves prevent backflow, while solenoid valves enable automated control. Each type of valve serves specific functions within HVAC systems, contributing to efficient and reliable operation.
