Applications:

The exhaust valves produced by our company are mainly used in independent heating systems, central heating systems, heating boilers, central air conditioning, floor heating, and solar heating systems, and other pipeline exhaust. Because there is usually a certain amount of air dissolved in water, and the solubility of air decreases with the increase of temperature, the gas gradually separates from the water in the process of water circulation, and gradually gathers together to form large bubbles or even air columns. Because of the supplement of water, gas is often generated.
