IVF Varioflow constant flow regulators

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 extract
- simple design
- good control characteristics
- easy adjustment of large installations
- low noise level

Construction

The flow regulator is made of galvanized steel sheet. Operating temperature -20° to +70°C. The control gear 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 its 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.
