10pcs Automatic Exhaust Valve 1/2" Garden Irrigation System Air Vent Valve Water Pipe Fitting

• 1. 【Flexible】: This vacuum intake and exhaust valve is a dynamic fast intake and exhaust valve, with a small volume of 10pcs, suitable for various irrigation system applications, using composite aerodynamics design, fast intake and exhaust speed.
• 2. 【Use】: The valve body adopts a straight channel design, the inlet and outlet diameters are large, and the flow rate is large, which can avoid the accumulation of air, prevent the formation of negative pressure, and have good sealing performance under low pressure.
• 3. 【Principle】: During the water injection process of the system, a large amount of air is quickly discharged from the intake and exhaust ports; after the water enters the air valve chamber, as the liquid level rises, the floating ball closes the rapid intake and exhaust ports.
• 4. 【Safety】: The sealing float has a long moving stroke to prevent the float from being blown up by high-speed airflow and cause the exhaust port to close prematurely. It can maintain good sealing performance under low pressure (0.3bar) and avoid water leakage.
• 5. 【Application】: When the system is under pressure, the intake valve and exhaust valve remain closed. When the system empties, a negative pressure differential is created and the air pushes the float down. The power quickly enters and the exhaust port opens, and the air enters the air valve to avoid negative pressure in the system.
