HVAC control valves are an important part of any heating, ventilation, and air conditioning (HVAC) system. They are responsible for controlling the flow of air and water through the system, ensuring that the temperature and humidity of the air is kept at the desired level. Control valves are typically located near the air handler, and they can be manually adjusted or automated to respond to changing conditions. They can also be used to regulate the flow of water to the heating or cooling system, allowing the user to control the temperature of the air. HVAC control valves are designed to be reliable and efficient, and they are typically made from durable materials such as brass or stainless steel. They are available in a variety of sizes and configurations, and they can be used to control the flow of air and water in both residential and commercial HVAC systems. HVAC control valves are an essential component of any HVAC system, and they are necessary for ensuring the proper functioning of the system.
