Area of use
The BEV-F is a single-stage valve offering only the function of the second ventilation stage (fine ventilation) provided by the two-stage valve (BEV-GF). For ventilation quantities of 20 to 40 m3/h. Specific applications include high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required, as well as at high points with low flow quantities.

Product features
- Type F (fine ventilation): Air escapes through this valve, and collected gases cause it to open once again, including under operating pressure, until the medium continues to flow and close the valve again.
- Installed at high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required.
- Installed at high points of pressure lines with low flow quantities.
