Ventilation Valve

To prevent underpressure in the pipework system

Ventilation valves are technical attachments that are usually used in drainage systems of buildings, which would be hindered by an underpressure in the pipework system. The ventilation valves allow air into the pipework system, by which both the underpressure can be balanced out and the intake of seal water can be prevented.

The ventilation of lifting systems is to be undertaken according to EN12056-1.
