Description
KARA-Anti shock Combination Air Release Valve
Features:
– Advanced design with a 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 a sonic air velocity.
– For the potential water hammer location or transmission pipeline, we should use an anti-shock combination air valve to prevent damage or impact of severe water hammer.
– An anti-shock device is installed on top of the bonnet, It will slow down the exhausting air flow out during filling to prevent hammer impact, whenever a vacuum happens, the device will drop down and let Large air into the pipeline.
– There are no arms or levers to prevent vibrating, bending, or direct closure of the float.
– Smooth barrel outside of the float, keep the float moving in the specified guide rail.
– Guide barrel buffer for collision prevention, and drain easily with proper holes around the barrel during vacuum.
– Outside screens will be an option for safety and to prevent insects or birds.
– 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 BS EN 558 and ANSI flange.
