Model No.: AV026
The AV026 Combination Air Valve for Sewage combines an air and vacuum large orifice and an automatic small orifice in a single body. The valve is specially designed to operate with liquids carrying solid particles such as sewage and effluent.The combination air valve discharges air (gases) during the filling or charging of the system, admits air to the system while it is being emptied of liquid and discharges accumulated air (gases) from the system while it is under pressure and operating. The valve's unique design guarantees complete separation of the liquid from the sealing mechanism and provides optimum work conditions.
Pump stations for sewage, waste water & water treatment plants.
Sewage water, effluent water and sea water supply lines.
Those features are achieved by:
The conical body shape and the external lever designed to: maintain the maximum distance between the liquid and the sealing mechanism; so as to obtain minimum body length.
Spring loaded joint between the stem and the upper float.
Vibrations of the lower float will not unseal the automatic valve.
Release of air will occur only after enough air accumulates.
Funnel-shaped lower body is designed to ensure that residues sewage matter will fall back into the system and be carried away by the main pipe.
All inner metal parts made of stainless steel.
Unique design of external lever prevents contact between the sewage and the sealing mechanism and clogging by floating solids, ensuring drip tight sealing.
Air Release valves function to release air pockets that collect at each high point of a pressured pipeline. Air Release Valves can open against internal pressure, because the internal lever mechanism multiplies the float force to be greater than the internal pressure. This greater force opens the orifice whenever air pockets collect in the valve. Air Release Valves are essential for pipeline efficiency and water hammer protection.
Why remove air from a water system?
Every building services engineer knows that air trapped in either a hot or chilled water system can cause trouble, such as excessive noise, corrosion and increased maintenance costs. Air can cause air locks which
inhibit the filling of the system or the priming of pumps. It can seriously affect the accuracy of flow measurement meters and regulating valves. Under extreme conditions it may even temporarily decommission plant.
Air and other incondensable gases considerably reduce heat transfer efficiency. A film of air 1 mm thick presents the same barrier to heat transfer as a wall of copper 13 m thick!
Entrapped air in any water system is a threat to thermal efficiency. It is particularly damaging in a chilled water system which does not have the natural deaerating ability of hot water.
