Types of Zone Control Valves by Actuation

Zone valves open and close using one of a few actuation methods, which affects response time and what control system they pair with.

Type

How It Works

Typical Use

Motorized (24V)

A small electric motor opens and closes the valve on a low-voltage signal

Most residential and light commercial zoning

Pneumatic

Compressed air opens and closes the valve

Older commercial buildings with existing pneumatic controls

Electric/Thermal

A heat-activated element opens the valve a few minutes after power is applied

Simple residential zoning, slower response than motorized

2-Wire vs. 3-Wire Zone Valves

Zone valves are also classified by wiring. 2-wire valves open when powered and close by spring return once power is cut, wiring directly to a thermostat or zone panel. 3-wire valves add an end switch that signals the boiler or circulator to turn on once the valve is fully open, which most modern zoning systems use for tighter control. Confirm your existing wiring configuration before ordering a replacement valve.

Frequently Asked Questions

Zone control valves are used in HVAC systems to regulate the flow of air or water to different zones of a building. By controlling airflow or water circulation, they help manage temperature in specific areas, providing customized comfort.

See the table above for how each actuation type works. We stock zone control valves, including motorized, pneumatic, and electrical models for residential and commercial systems.

The right valve depends on factors such as the size of your system, the type of HVAC system, and the type of zones you're controlling. Our customer support team can help you select the appropriate valve based on your needs.

While installation is possible for some systems, it's important to follow manufacturer instructions carefully to ensure proper operation. If you're unsure, it's advisable to consult a professional HVAC technician.

Regular maintenance includes inspecting the valves for wear and tear, checking for leaks, and ensuring that the control mechanism is functioning properly. Periodically cleaning the valve and its components will help maintain optimal performance.
