The AV155 Industries Simple Lever air release valve automatically releases air that collects at high points in the system, which increases operating efficiency and reduces cost. It has a relatively large standard orifice to minimize plugging and a Buna-N seat, rendering it suitable for both hot (up to 180° F) and cold water applications.

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.

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.

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.
