Triple Function Large Air Exhausting Small air venting vacuum breaker Combination Sewage Air Release Valve​

Feature

Combination kinetic air release valve provide 3 functions:

1.Large air release during fi lling of the pipeline.

2.Small air release under pressurized pipeline.
3.Large air intake during draining of the pipeline.

. 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.
. No arms or levers to prevent vibrating, bending, direct closure of the fl oat.
. Smooth cage outside of the float, keep float moving in specifi ed guide rail.
. Bottom rubber buffer for collision prevention, and drain easy with proper holes around the cage 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 EN1074-4, AWWA C512
. Flange drilling and dimension meets BS EN 1092 and BS EN 558 and ANSI flange.
