Description The GOLO™ intelligent air valve is a high precision, low airflow measurement and control terminal unit that uses a patented variable orifice plate technology. The unique design provides stable and precise airflow control over the entire range of room airflow requirements with a single unit size. By upsizing the GOLO valve over a traditional terminal unit pressure drop is reduced lowering both sound and energy usage.
