Combination Air Valve for Wastewater Sewage Automatic Air Valve

Tianjin U-ideal Combination Air Valve for Wastewater
AV020 Combination Air Valve discription:
The AV020 Combination Air Valve combines an air & vacuum orifice and an air release orifice in a single body. The valve is specially designed to operate with liquids carrying solid particles such as wastewater and effluents. The combination air valve discharges air (gases) during the filling or charging of the system, admits air into the system while it is being emptied of liquid and releases accumulated air (gases) from the system while it is under pressure and operating. The valve's unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.
 The valve is specially designed to operate with liquids carrying solid particles such as sewage and effluent.
Product Features
Specially designed to operate with liquids carrying solid particles such as wastewater and effluents.
Unique "air gap" design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.
Combines the features of both an air & vacuum valve and an air release valve.
Triple function:
Air & vacuum component discharges large volumes of air during filling of the system.
Air & vacuum component admits large volumes of air during drainage and at water column separation.
The air release component releases entrapped air in pressurized systems.
AV983 Combination Air Valve discription:
The AV983 Air & Vacuum Valves are specially designed to operate with liquids carrying solid particles such as wastewater and effluents. These air & vacuum valves discharge air (gases) during the filling or charging of the system and admit air into the system while it is being emptied of liquid. The valve's unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.

Product Features
Specially designed to operate with liquids carrying solid particles such as wastewater and effluents.
Unique "air gap" design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.
The valve design and float mechanism are less sensitive to pressure differentials enabling a comparably large orifice for a wide pressure range (up to 360 psi).
Double function:
Air & vacuum component discharges large volumes of air during filling of the system.
Air & vacuum component admits large volumes of air during drainage and at water column separation.

Applications for Tianjin U-ideal float-type air vents include hydronic heating systems, water service lines, water storage tanks, centrifugal pumps, gas lines, solvent filters and similar equipment. Operation is completely automatic, and the simple design and quality mechanism make operation trouble-free and maintenance infrequent.

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.
