Furnace Zone Valve Bodies

A zone valve body regulates the flow of heated water through a specific zone of a hydronic heating system, opening and closing in response to the connected actuator. Zone valve bodies are used in fan coils, baseboard heating, radiant systems, and other zoned hydronic applications.

Furnace Part Source carries a range of zone valve bodies for residential and light-commercial hydronic heating systems, including 2-way and 3-way configurations in multiple connection sizes.

Common Zone Valve Body Parts We Carry

Common replacement parts in this category include:

  • 2-way zone valve bodies for single-flow-path zone control.
  • 3-way zone valve bodies for diverting or mixing applications.
  • Sweat, NPT, and flare connection valve bodies for different piping configurations.
  • Modulating valve bodies for zones requiring variable flow control.

How to Find the Right Zone Valve Body

Before ordering, check the existing valve body for the part number, connection size, connection type, and Cv rating. Zone valve bodies are often paired with a specific actuator, so confirm actuator compatibility as well.

For best fit, compare:

  • Original valve body part number
  • Connection size and type, such as sweat, NPT, or flare
  • 2-way or 3-way configuration
  • Cv rating (flow capacity)
  • Compatible actuator type

Zone Valve Bodies From Leading HVAC Brands

Our catalog includes zone valve bodies from Erie, Schneider Electric (Erie), and Honeywell, covering a range of connection sizes, Cv ratings, and 2-way or 3-way configurations used across residential and commercial hydronic systems.

Need Help Matching a Zone Valve Body?

Not sure which zone valve body you need? Use the part number, connection size, and Cv rating from your existing valve to narrow the search, or contact Furnace Part Source for help identifying the correct replacement.

Zone Valve Body FAQs

What is the difference between a 2-way and 3-way zone valve body?

A 2-way valve body controls flow in a single path, either open or closed, while a 3-way valve body directs or blends flow between two paths, often used for diverting or mixing applications.

Can I replace the valve body without replacing the actuator?

In many cases, yes, since the valve body and actuator are often sold and replaced separately. Confirm that the replacement valve body is compatible with your existing actuator.

What does Cv rating mean on a zone valve body?

Cv rating indicates the flow capacity of the valve. Matching the Cv rating to the original valve helps maintain proper flow and system balance in the hydronic loop.

Do zone valve bodies work with different types of fluid?

Many zone valve bodies are compatible with water, glycol mixtures, and low-pressure steam, but always confirm compatibility with your specific system fluid before ordering.
