Product Description
Tianjin U-ideal Dual body Combination Air Vent Valve/Air valve,Air & Vacuum Valves are an efficient means to fill and drain pipelines.
Dual body Combination Air Vent Valve Design Features:
Combines the features of Air/Vacuum Valves and Air Release Valves. These valves are also called Double Orifice Air Valves. These valves are installed on all high points of a system where it has been determined dual function Air/Vacuum and Air Release Valves are needed to release air and also protect a pipeline from vacuum. Combination Air Valves are available in 2 body styles - 1) single body combination or 2) custom built combination with two bodies. The single body combination is used where compactness is preferred. Generally, it is sound engineering practice to use Combination Air Valves instead of simple purpose Air/ Vacuum Valves.
Air/Vacuum Valves are float operated, having a large discharge orifice, equal in size to the valves inlet. Air/Vacuum valves allow large volumes of air to be exhausted from or admitted into a water pipeline as it is being filled or drained. As the pipeline fills, water enters the Air Valve, raises the float and shuts-off. When draining the pipeline, the float drops, allowing air to enter, preventing vacuum, possible pipeline collapse or damaging water column separation. Air & Vacuum Valves are an efficient means to fill and drain pipelines.
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.
