Combination Air Valve (AWWA C-512)

Combination Kinetic air release valve provides 3 functions:

  • Air venting for small pockets of air release from pressurized piping system
  • Air/vacuum for large air exhaust during filling of the pipeline and
  • Admitting large volumes of air during draining of piping system.

  • Advanced design with simple mechanism, strong float to prevent cracking during sudden water hammer.
  • The float will still be at bottom level even up to air velocity about sonic velocity, until water rises to lift the float and seal the orifice.
  • No arms or levers to prevent vibrating, direct closure of the float.
  • Smooth cage outside of the float, keep float moving in specified guide rail.
  • Bottom impact rubber for collision prevention, and drain easy with proper holes around during vacuum.
  • Outside screen will be an option for safety and prevent insects or birds in.
  • Fully fusion epoxy coated inside and outside of valve body for long term services.
  • Manufacturing standard meets BS EN 1074-3, AWWA C512
  • Flange drilling and dimension meets IS 1538 and BS EN 558.
