IVF Varioflow constant flow regulators

Information

The IVF Constant Flow Regulator is used for automatic flow control for supply or exhaust air. It ensures a constant value of air flow regardless of the pressure conditions in the pipe network.

- for both supply and discharge
- simple construction
- good control properties
- easy adjustment 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 will drop the flow rate 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.
