Sewerage Air Valves Range
Air valves are used to protect waste water networks by evacuating air that has become trapped in pipelines.
A welded steel, epoxy coated body, and a mobile part that is made entirely of plastic, ensure they have excellent resistance to corrosion.
Their use allows savings to be made on mains laying : the pipe can follow the contours of the land, thereby avoiding extra costs (trench shoring, groundwater lowering, etc.) associated with having to dig very deep in order to follow a regular mains profile.
The single function low flow sewage air valve (5 M3/h) is available in DN80.
Maximal service pressure 16 bar. Flange ISO PN10.
- The air valve protects the pipeline by the air extraction in the pipelines high points.
- The valve body, in mechanically-welded steel, is protected by oven-baked epoxy-resin thickness 200 microns. The mobile clapper/float assembly is entirely made from plastic material, neutral to any corrosive aggression by the waste water.
- The use of sewage air valves is economic for the pipeline installation. By using air valves, the pipeline can follow the ground relief and avoid the cost of the necessary construction works to follow a regular pipeline profile.
The double high flow sewage air valve (430 M3/h) is available in DN80, DN100 & DN150.
Maximal pressure service10 bars. Flange ISO PN10.

The triple function high flow (430 m3/h) and low flow (5 m3/h) is available in DN80, DN100 & DN150.
Maxi pressure 16 bar. Flange ISO NP10.
- Functions of the air valve :
- 1- Air outlet with high flow : pipeline filling
- 2- Air blowing-off in pressure : pipeline in normal service
- 3-Air inlet with high flow :pipeline draining
