Single Thread Bleed Valves are commonly used on pipelines for independent heating systems, central heating supply systems, heating boilers, central air conditioning, floor heating and air heating systems.
Water contains dissolved air. As temperature rises, air solubility reduces and air separates out from the water. In the water circulation process, separated air accumulates to form big bubbles or air columns. Gas can also be introduced via makeup water.
