Tianjin U-ideal Air Vent valve for Solar Water Heater, Air release valve with Check Valve

Automatic air vent valve in brass with silicone rubber plug
Automatically dispose of trapped air bubbles in a system
Includes manual venting outlet
Compact design to allow installation in applications with limited space
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.
These Air vent are compact float-type valves for the removal of air and other gases from hydronic heating and cooling systems, liquid chilling operations, and other light liquid services.
The Air vent valve is designed to release air-pockets out of the piping system.I t should be installed at every high-point of the piping system where air can be trapped. The simple construction relies on a float held by a lever,so that the float does not rub against the body to avoid any risk of jamming.

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.
 
Air Valves vs. Hydrants 
There is a common misconception that fire hydrants can be used in place of combination air valves to provide the required air-release service. This method should be strongly discouraged for several reasons: 
The use of fire hydrants requires active user intervention, which creates a hidden maintenance cost. In order to be effective, the hydrants should be discharged once per day. At just five minutes per hydrant at a rate of $10.00 per hour, a small town with twenty hydrants would spend more on the labor used than it would have spent on twenty automatic air valves. 
Manual air release cannot accommodate surges in flow or demand. Only automatic air valves can provide the needed functions on demand in order to protect the water system. 
Hydrants cannot provide the vacuum-breaking function required to prevent contamination during negative-pressure events. Automatic air valves help protect the finished water at all hours, every day of the year. 
The pressures accumulated within the hydrant, even at a system pressure of 80 psi, can be extremely hazardous to maintenance workers. Accumulated pressures in some systems can reach more than ten times the rated system water pressure. Automatic air valves work without user intervention and prevent the accumulation of pressure. 
Hydrants are typically mounted to the sides of a main (at the 3 o'clock and 9 o'clock positions), rather than at the top. This can significantly reduce their effectiveness as air-release devices, even when flanged at the full diameter of the main. Automatic air valves are properly installed only at the top (12 o'clock) position, where they can provide complete discharge of accumulated air.
