  • Advanced design with simple mechanism, strong float to prevent cracking during sudden water hammer & quick closure.
  • Aerokinetic mechanism to resist blow shut under higher air velocity even up to sonic velocity of air.
  • With special fat body design to lower the sewage water flow speed, and let the air out but keep sewage water underneath.
  • Keep dirty or corrosive liquid inside the body for safety during operation and no harm to human & surrounding environment
  • Internal body guide and upper round wall keep float moving on its rail and keep liquid turbulence flow within this area.
