Exhaust Air Disc Valve

This exhaust air disc valve Revit family is a ceiling-mounted HVAC terminal component featuring a clean, circular design. The exhaust air disc valve features a minimalist, circular profile engineered for ceiling installation in ventilation systems. It consists of a central adjustable disc plate and a perimeter housing, finished in a standard white powder-coated aesthetic. The geometry is straightforward, focusing on functional airflow regulation while maintaining a low-profile presence on ceiling surfaces. The assembly is designed to integrate seamlessly into suspended or hard-ceiling finishes, providing a consistent look across mechanical layouts. Its construction is lightweight and robust, typical of standard steel air terminals used in commercial and residential HVAC applications.

The download is a 399 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

In Revit, this component functions as a host-based family for ceiling surfaces. Users can insert the valve directly into reflected ceiling plans or 3D views, where it snaps to the ceiling plane. Parameters allow for standard mechanical connection sizing to match ductwork requirements. The family is built to support schedules, allowing for easy extraction of counts and specifications within the project browser. Use standard alignment and dimensioning tools to position the valve accurately according to mechanical layout requirements.
