Agriculture Farm Plastic Air Valve Irrigation Pipeline Pressure Release Valve for Water Line

Product DescriptionAir release valve for drip IrrigationFeaturesInlet and exhaust air valves are suitable for various irrigation system applications.When the system is filled with water, the air valve discharges a large amount of air in the pipeline; when the system is emptied, the air valve draws in a large amount of air to prevent vaclium negative pressure. The valve adopts advanced composite gas dynaimics design,with rapid intake and exhaust; it can avoid air accumulation, prevent the formation of negative pressure, and has good sealing performance at low pressure.PRODUCT ADVANTAGE  1. Valve body adopts DC channel design, large exhaust size, large flow. 2. The sealing floating ball has a long moving stroke,which can prevent the floating ball from being blown up by high-speed airflow, leading to the premature closure of the exhaust port, and does not affect the air inhalation or exclusion. 3. Low pressure seal - good sealing at low pressure (0.2BAR) to avoid water leakage. 4. All components have corrosion resistance, low maintenance frequency and long service life.
