Features
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 float.
Smooth cage outside of the float, movement restricted to specified guide rail.
Bottom rubber buffer for collision prevention and easy to drain with proper holes around the cage during vacuum.
All iron parts are coated inside & outside with fusion bonded epoxy for corrosion resistance as per AWWA C550.
Suitable for distribution pipeline. For pipeline with high risk of water hammer, anti-shock device is advised.
Combination Air Release Valve fully complies with manufacturing standard AWWA C512 and BS EN 1074-4.
1" to 2" available in threaded connection. 2" to 12" available with ANSI Class 125 and Class 150 flanges.
Valves are certified NSF61 for Drinking Water and NSF372 for Lead Content.
