Main features

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.
