Application:

When running or heating, water would release gas. If cannot be exhausted promptly, those gas will  be led to a bad result, such as corrosion and capitation. So the system needs to install a valve to 

exhaust gas. On the other hand, when there is a pressure drop, a valve which can permit air to enter

 is necessary. Breather valve can not only vent air, but also avoid siphoning.

 Thus many systems install breather valves: independent heating system, central heating system,  solar system, central air conditioning, and boiler.

Feature:

1All valves have been tested prior to shipment; ensure that the valves will not exhaust water during working.
2. Automatically open to inhale air in case of negative pressure when there is a vacuum. 
3 .The valves will keep on doing the work to protect system when there is a pressure.
4. The body and elements are made by stainless steel 304.That can make sure the valve can work for a longer working life.
