Double function air valve high flow 430m³/h PFA 10 bars

Product family
Pipeline protection

The double high flow sewage air valve (430 M3/h) is available in DN80, DN100 & DN150.

Maximal pressure service10 bars. 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.

Check valve option

When the user doesn’t want air entry, a check valve can be adapted on the air outlet (on request)

Security system by excessive flow option

During the pipeline filling and when the pumps stop, the security system limits the water hammer in limiting the air exit with high flow by an automatic valve. The adjustment of the valve activation is defined by the user in the order (on request)

Installation, put into service, maintenance

  • The manhole must be ventilated.
  • The sewage air valve is installed in vertical position on a shut-off valve to operate on the air valve without disturbing the pipeline.
  • Draining by a ¾ inch outlet.
  • For the maintenance or the rinsing, the complete mobile set can be extracted by the dismantling superior part (no need to dismount the air valve).
  • The nozzle can be connect in his superior part to a pipe.
