Ruud 7URD Zone Damper 7 Inch Round 3-wire 24V

Product Description

The RUUD 7URD is a 7-inch round zone damper designed for residential and light commercial HVAC zoning systems. Operating on 24 volts AC at 1.5 VA, it uses a 3-wire power open/power close actuator configuration, giving the zone controller positive damper position in both directions. Rated at 160 CFM, it regulates conditioned airflow within ductwork when paired with a thermostat-based zone control panel. Licensed HVAC technicians install this damper as part of a multi-zone forced-air system to direct heating or cooling to individual zones independently.

This damper is suited for residential forced-air zoning applications where individual room or zone temperature control is required. The round 7-inch body fits standard round ductwork of the same diameter. The 3-wire, power close/open design is compatible with most residential zone control panels that provide a dedicated close signal, ensuring the blade moves to a fully closed or fully open position on command rather than relying on spring return.

Key Features

• 7-inch round body sized for standard round duct installations
• Power open and power close (3-wire) actuation for positive blade positioning
• 24 volts AC, 1.5 VA low-voltage control circuit
• 160 CFM airflow rating
• Compatible with thermostat-driven zone control systems

Compatibility

Designed as an OEM-style replacement zone damper for 7-inch round duct thermostat zoning systems requiring a 3-wire, 24-volt power open/power close actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler and de-energize the zone control panel before wiring or mounting the damper. The 3-wire harness must be connected per the zone control panel manufacturer wiring diagram. Ensure the damper blade rotates freely and the duct collar is sealed with approved tape or mastic after installation to prevent air leakage.
