Product Overview
Exhaust valves are usually applied on the pipelines of independent heating system, central heating supply syestem, heating boiler, central air-conditioning,floor heating and air heating system . Because there are certain air soluble in water, and the air solubility decrease when the temperature rise,then the air separate from water during water cycle, it gradually comes together to form larger bubbles or air column, it usually produce gas for the water supplement.
