Product Introduction：

An automatic air vent valve is a device that automatically removes air using an internal opening and closing mechanism. 

It is mainly used in hot water heating systems, fire sprinkler systems, and HVAC systems. 

It employs a float-based opening and closing mechanism: when the valve is full of water, the float rises and closes the vent; when air accumulates and the water level drops, the float, under its own weight, falls and opens the vent to release air; and when the system is under negative pressure, it draws in outside air to prevent hazards.

Application:

Essential components for water supply and drainage, floor heating pipes, central air conditioning water circulation pipes, and fire protection water supply pipes;

Continuous removal of gas accumulation in the pipeline to solve problems such as gas blockage, reduced water flow, abnormal noise and vibration of the pipeline, cavitation of the water pump, and pipeline gas resistance;

Installed vertically at the highest point of the pipeline (where the gas accumulates), it is a standard small valve for the water and heating pipeline network.
