1、The vacuum intake and exhaust valve is a dynamic fast intake and exhaust valve, suitable for various irrigation system applications.
2、When the system is filled with water, the air valve discharges a large amount of air in the pipeline, and when the system is emptied, the air valve sucks in a large amount of air to prevent vacuum negative pressure.
3、The valve adopts advanced composite gas dynamics design, with fast inlet and outlet.
4、It can avoid the accumulation of air, prevent the formation of negative pressure, and has good sealing performance at low pressure.
5、Small size, simple structure and reliable performance. The valve body adopts a straight‑through channel design, with large inlet and outlet sizes and large flow. 6、6. The sealed floating ball has a long moving stroke‑to prevent the floating ball from being blown up by the high‑speed airflow and causing the exhaust port to close prematurely, and it does not affect the air intake or discharge. 7、7. Power low‑pressure sealing‑it can maintain good sealing performance under low pressure (0.3bar) to avoid water leakage. 8、8. All parts are made of new materials and have a long service life. 9、9. 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, the floating ball closes the quick intake and exhaust ports as the liquid level rises. 10、10. The aerodynamic valve body design and the floating ball anti‑blow‑up design can prevent the floating ball from being blown up by the high‑speed airflow before the water enters the air valve and causing the exhaust port to close prematurely. 11、11. When the system is emptied, a negative pressure difference is formed, and the air pushes the float downward. The power quick intake and exhaust ports are opened and air enters the air valve to avoid negative pressure in the system. 1
2、12. When the system is under pressure, the intake and exhaust valves are kept closed.
