Automatic exhaust valve is a functional valve used in heating systems such as radiators, floor heating, and boiler systems to remove system air. It is often installed at the highest point of the system, or directly used with water distributors and radiators. The main purpose is to remove the internal air and fill the radiator with warm water to ensure the room temperature.

1. The automatic exhaust valve must be installed vertically, that is, the buoy inside must be in a vertical state, so as not to affect the exhaust;
2. When installing the automatic exhaust valve, it is best to install it together with the isolation valve, so that when the exhaust valve needs to be removed for maintenance, it can ensure the airtightness of the system and prevent water from flowing out;
3. The automatic exhaust valve is generally installed in the pipeline part where the system is easy to collect gas, such as the highest point of the system and the highest point of a section of pipeline, which is conducive to smooth exhaust.
