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. The solution includes a VAV terminal with reheat, all controls and hydronics factory preassembled
and leak-tested as a complete package to reduce field installed costs.
