Automatic Air Vent Valve; Bronze Air Release Valve

Tianjin U-ideal Air vents to remove air from pipelines carrying liquids.

Main Applications:Air conditioning facilities, solar systems, water transport lines, water storage tanks.Transport of and facilities using other fluids.Water, hot water, other liquid other than toxic or flamable

Benefits and Features
Automated Air Venting During OperationAir entering the automatic air vent is rapidly discharged, even during water or liquid transport or during operation.The float responds with great sensitivity to condensate levels, automatically opening and closing the valve and thereby eliminating the need for manual labor.
Long Service Life
The float is the only moving part. Simple design, with no hinges or levers.
Tight Sealing
The grounded float and rubber valve seat prevent leakage 
The precision-grounded float and 3-point seating prevent leakage 

Application Areas
For use in applications requiring the steady discharge of air - both initial air and air generated during operation.
For applications requiring the discharge of large quantities of initial air, also install a rapid initial air vent.


Air vent valves
are used to allow the pressure in the tank to balance while preventing the spillage of the fluid through the vent lines. These valves allow the free flow of fluid or air in or out of a chamber or tank until they close, usually activated by a float.
During refueling, incoming fuel dis-places the air in the tank. The vent valve allows this air to escape through a designated vent path
When the tank is full, the float valve closes preventing the fuel from escaping. These valves also allow air to re-enter the tank as fuel is consumed, preventing dangerous negative pressure and potential fuel starvation. Vent valves protect the fuel tank from pressure damage resulting from expansion and contraction of the fuel due to changes in temperature. In some applications they incorporate measures to prevent the fuel from exiting the tank when the aircraft is inverted either during flight or in an emergency.
