Air Release Valve

The air valve is used in independent heating systems, centralized heating systems, heating boilers, central air conditioning, underfloor heating, and solar heating systems for pipeline venting.

Since water usually contains a certain amount of dissolved air, and the solubility of air decreases as the temperature rises, gas gradually separates from the water during circulation and tends to accumulate, forming large bubbles or even gas columns.

With the continuous water supply, gas is often generated.
