Product Overview
Air vlaves are applied on the water pipelines, as the equipment to exclude the gas in pipelines, it enhances the efficiency of water transport and protect the pipelines from transformation and broke.When the pipeline under negative pressure, this valve will suction air automatically to prevent the pipeline broken. This valve has big gas displacement for double airvents, it owns maintenance valve, close it when repair, then it can be on-line overhaul.
