performance diagram
Mode of operation
- Infinite automatic aeration and ventilation valve for waste water, untreated water and drinking water. The infinite variable aeration and ventilation is done via a mesh seat with a rolling membrane system. The seal seat does not come into contact with the waste water, so it prevent the seat from getting blocked up and thus provides high operational safety.
Characteristics
- Self-acting
- All parts are corrosion resistant
- Efficient purging during maintenance work.
- On request, the aeration and ventilation valve is also available in the colour blue or in the material INOX.
Material
- Housing, cover and flange: ST 37 with EWS-coating (Inox on request)
- Diaphragm holder (mesh): POM
- Membrane: EPDM
- Float ball: POM
- Outlet bend d 50: PE 100
