Where Should Air Valves Be Placed?  Air valve installation requirements  1. The Air valve must be installed vertically, that is, it must be ensured that the internal float is in a vertical state, so as not to affect the vent;  2. When installing the air valve, it is best to install it together with the isolation valve, so that when the air valve needs to be removed for maintenance, the system can be sealed and water will not flow out;  3. The air valve is generally installed at the highest point of the system, which helps to improve the venting efficiency.  Air valves are generally installed at the commanding heights of the heating system.  1. The floor heating automatic air valve must be installed vertically on the ground, and the float in the valve body must be in a vertical state, and it cannot be installed upside down or horizontally;  2. Since the gas density is smaller than that of water, the vent device will climb along the pipeline to the highest point of the system and gather there. In order to improve the vent efficiency, the air valve is generally installed at the commanding height of the heating system;  3. In order to facilitate the maintenance of the floor heating system, the air valve is generally used together with the isolation valve, so that the system does not need to be shut down to remove the air valve;  4. After the floor heating automatic venting device is installed, the nut must be loosened to vent, but do not unscrew all of it, beware of a lot of water running, and remember to tighten the dust cap after venting.
