Zone Valve Actuators

Zone valve actuators control the opening and closing of zone valves in hydronic heating and multi-zone HVAC systems, directing heated water to specific zones as needed. A properly functioning actuator is important for accurate zone control, energy efficiency, and consistent comfort throughout a building.

Furnace Part Source carries a range of zone valve actuators and replacement powerheads for residential and light-commercial hydronic heating systems, including standalone actuators and full zone valve assemblies.

Common Zone Valve Actuator Parts We Carry

Common replacement parts in this category include:

  • On/off actuators that fully open or close the valve based on zone demand.
  • Normally open and normally closed actuators for different zone valve configurations.
  • Actuators with auxiliary end switches used to signal a circulator pump or control board.
  • Replacement powerheads and motors for rebuilding an existing zone valve body.

How to Find the Right Zone Valve Actuator

Before ordering, check the existing actuator or zone valve for the model number and part number. Confirm the voltage (commonly 24V or 120V), the switching configuration (normally open or normally closed), and whether the application requires an auxiliary end switch.

For best fit, compare:

  • Original actuator part number
  • Voltage, such as 24V or 120V
  • Normally open (N/O) or normally closed (N/C) operation
  • Presence of an auxiliary end switch
  • Valve body size and connection type, if replacing a full assembly

Many actuators use a direct-coupled, tool-free connection to the valve body, which can simplify replacement without needing to remove the valve itself from the piping.

Zone Valve Actuators From Leading HVAC Brands

Our catalog includes zone valve actuators and powerheads from Erie, Schneider Electric (Erie), and Honeywell/Resideo, covering a range of voltages and switching configurations used across residential and commercial hydronic systems.

Zone Valve Actuator FAQs

What does a zone valve actuator do?

A zone valve actuator opens or closes a zone valve to control the flow of heated water to a specific zone, allowing different areas of a building to be heated independently.

Can I replace just the actuator without replacing the whole zone valve?

In many cases, yes. Many actuators are designed to be replaced separately from the valve body using a direct-coupled, tool-free connection, provided the replacement matches the original voltage and configuration.

What is the difference between normally open and normally closed actuators?

A normally closed actuator keeps the valve closed until powered, while a normally open actuator keeps the valve open until powered. Always match the original configuration when replacing an actuator.

Do I need an actuator with an auxiliary end switch?

An auxiliary end switch is needed if the actuator must signal another component, such as a circulator pump or control board, once the valve reaches the open position. Check your system wiring to confirm.
