Single Orifice Air Valve

QB1, P1 single port exhaust valve this product is used at the point or closed place on the pipeline to discharge the gas in the pipeline and dredge the pipeline to make the pipeline operate normally during operation. The exhaust valve is connected with two kinds of screw threads and flanges.

Function and principle
A certain amount of air is usually dissolved in the fluid medium of the pipeline, and the solubility of air decreases with the increase of temperature. In this way, during the circulation of water, the gas gradually separates from the water and gradually gathers together to form large bubbles or even gas columns. Due to the supplement of water, gas is often generated, At this time, the exhaust valve needs to be used to empty the excess gas in the pipeline to ensure the smooth flow of the medium. The valve is used for pipe exhaust of independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system.
