Anti shock Combination Air Release Valve
. 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.
. For the potential water hammer location or transmission pipeline, we should use anti shock combination air valve to prevent from damage or impact of severe water hammer.
. Anti shock device is installed on top of bonnet, It will slow down the exhausting air flow out during filling to prevent hammer impact, whenever vacuum happen, the device will drop down and let Large air into the pipeline.
. No arms or levers to prevent vibrating, bending, direct closure of the float.
. Smooth barrel outside of the float, keep float moving in specified guide rail.
. Quide barrel buffer for collision prevention, and drain easy with proper holes around the barrel 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 or exceeds BS EN 1074-4, AWWA C512
. Flange drilling and dimension meets BS EN 1092 and BS EN 558 and ANSI flange.
Combination air release valve with anti shock device provides 3 functions: 1.Restricted air release during filling of the pipeline. 2.Small air release under pressurized pipeline. 3.Large air intake during draining of the pipeline.
For clean water system, transimission and distribution, irrigation system.
