Air Release Valve

• 
• Product Code: Air Release Valve

Combination Air Release Valve

Functions

·         Large air release during filing of the pipeline.

·         Small air release under pressurized pipeline.

·         Large air intake during draining of the pipeline.

Features

·         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.

Anti-shock Air Release Valve

Functions:

·         Suitable Restricted air release during filling of the pipeline.

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

·          Protected against water hammer in the pipeline.

Features:

·         Advanced design with simple mechanism along with strong float to prevent cracking during sudden water hammer & quick closure. Aerokinetic mechanism to resist blow shut under high air velocity even up to sonic velocity of air.

·         For the potential water hammer area or transmission pipeline, it is recommended to 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 during filling to prevent hammer impact, under vacuum condition, the device will drop down and let large air into the pipeline.

·         No arms or levers.

·         This prevents vibrating, bending, direct closure of the float.

·          Smooth barrel outside of the float, controls float movements within specified guide rail.

·         Guide Barrel is equipped with a rubber buffer to prevent collision between the float and the barrel. Draining is facilitated by addition of holes on the side of the barrel

·         All iron parts are coated inside & outside with fusion bonded epoxy for corrosion resistance as per AWWA C550.

·         Anti-shock Air Release Valve fully complies with manufacturing standard AWWA C512 and BS EN 1074-4.

Sewage Air Release Valve

Features:

·         Large air release during filing of the pipeline.

·         Small air venting under pressurized pipeline.

·         Large air intake during draining of the pipeline.

·         Advanced design with simple mechanism, strong stainless-steel 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.

·         100% Spill Free: Enlarged body specially designed to lower the sewage water flow speed, short stroke designed for quick closure and internals shape engineered to prevent splash even with turbulent flows.

·         Keeps dirty or corrosive liquid inside the body for safety during operation and prevents harming operators & surrounding environment.

·         Internal body guide and upper round wall restrict float movement on its rail and keep liquid turbulence within this area.

·         Much larger air flow through the nozzle even for higher viscosity liquid.

·          All iron parts are coated inside & outside with fusion bonded epoxy for corrosion resistance as per AWWA C550.

·          Sewage Air Release Valve fully complies with manufacturing standard AWWA C512 and BS EN 1074-4.
