Air Valve
Avishkar Engineers Pvt. Ltd. has designed and developed Air valve as per AWWA C 512/IS 14845. Valve size range is 50mm to 200mm. Many pipeline problems are caused by lack of proper aeration and de-aeration of the pipeline. Air in the pipeline can cause extensive and expensive damage to the pipeline, among others due to pressure surges.

Advantages
Natural Anti – Surge
Due to very good flow rate, it will eliminate the need of a secondary anti-surge orifice plate. Therefore our design is natural anti-surge in combination with rest of our design.

Resistance - Free Flow
The flow is limited to nominal diameter area, only at inlet and outlet. The rest of the path has bigger area than the nominal diameter and this reduces the flow velocity locally. Lower flow velocity means lower resistance. Due to low height of the valve, the air travel less distance, and this also reduces resistance.

Low Pressure Sealing
Air valve seal badly at low pressures. The unique design of the float ensures that our air valve is observed to be drop tight at 50cm water column. (Height above sealing surface level, tested on DN 200). This is equal to a pressure of 0.05 bars. In general production we test the valves at 1m water level and as a precaution we promise sealing at 2m of water in site conditions. So our low-pressure sealing is declared at 2mwc.

High Pressure Sealing
Our valves are shell tested to PN 2.0 at design stage, however the burst pressure is much higher, due to careful selection of materials and the design itself. Under normal testing we test our valves at PN x 1.5. The cover plate for the orifice is made of carbon steel; it may elongate under high surge pressure but will not break.

Robust, But High Floatation Rate
The steel floats if they are strong, cannot float well. Solid cylindrical floats are very strong versus pressure, but their floatation rate is low. ABS plastic (hollow) floats are generally weak versus unexpected pressure surges. Our floats are made of industrial plastic, with thick walls, but still empty inside. The result is a float that is strong enough to cope with surges, while having a good floatation rate
