RVP-R - VAV regulators
VAV regulators are used for automatic airflow regulation in the ventilation and air conditioning systems. They adjust the amount of supply/exhaust air to control the climate individually for every room/zone served.
By using the control elements they can adjust accordingly to different heat gain/loses in the zones served with respect to amount of people gathered in the zone and also other factors such as heat gains and loses through the windows.
RVP-R regulators may be produced in two types with respect to the acting time. In the standard version time necessary for the full cycle (open to close) is 150 seconds, while the fast acting drive can do that in 3 seconds.
In the special type RVP-R regulators may also be applicable to work with contaminated air with light corrosive gases (according to Classification of Corrosive Environments ISO 12944 max. class C3).
