Information
The MVF constant flow regulator for circular ducts is used for automatic control of supply and extract air flow. It ensures a constant air flow value regardless of the pressure conditions in the pipe network.
- for both supply and exhaust
- simple construction
- good control properties
- simple regulation of large-scale installations
- low noise level
Construction
The flow regulator is made of galvanized steel sheet. Operating temperature -20° to +70°C. The control unit is fixed to the desired flow rate. When the air flow rate is increased, the pressure differential in the regulator increases and the damper closes, thus reducing the valve flow cross-section. This causes the flow rate to drop back to the original value.
Caution
When designing and installing, care must be taken to ensure that the line pressure does not exceed 1000 Pa and that the minimum pressure loss is as shown in the chart. Otherwise, the regulator will not perform its function and may be a source of noise.
