ZONE VALVE

What are Zone Valves in HVAC?

In HVAC systems, zone valves are components that manage the flow of water or steam to various zones or areas within a building, allowing for independent temperature regulation and enhancing energy efficiency.

Zone valves are particularly utilized in hydronic heating or cooling systems, providing the ability to control temperatures in different areas of a building individually.

Many people often confuse solenoid valves with zone valves. To clarify, solenoid valves are electrically operated valves that open or close a flow path using an electromagnet. In contrast, zone valves, which are typically motorized ball valves, specifically regulate water flow to designated zones within a heating or cooling system.

In essence, solenoid valves are installed within HVAC systems to manage fluid activity, while zone valves are located outside the HVAC systems, often in building areas, to control fluid activity in specific zones.

Types of Zone Valves:

• Two-way valves: Can either open or close, permitting full flow or no flow at all.
• Three-way valves: Can redirect fluid flow between two zones or blend hot and cold fluids to achieve a desired temperature.

For selecting durable and high-quality products, we recommend reputable zone valve manufacturers such as Honeywell, Johnson Controls, and Aira.
