Product Overview
The threaded air vent valve is used for venting pipelines in independent heating systems, central heating systems, heating boilers, central air conditioning systems, floor heating systems, and solar heating systems. Since water usually contains dissolved air, and the solubility of air decreases as temperature rises, air gradually separates from the water during circulation and accumulates to form large air bubbles or even air columns, which hinders heat transfer in the heating system.
