Simple structure and reliable performace.Valve is of straight flow channel with large aire inlet and olet as well as large flow.Long movemnet stroke of seal float ball protects the float ball from blowing by highspeed airflow and avoid too early close of air outlet. Meanwhile, it doesn't imact air suction or discharge.Good sealing performance at low pressure(0.2bar) and avoidance of water leakage for dynamical low-pressure seal.
1.Air &vacuume relief valve are applied to a variety of irrigation systems. When water is injected to systems, a large amount of air is discharged from pipelines by the valve; While the water is emptied,the valve inhalesa large quantity of air to prevent vacuum negative pressur.
2.With advanced compound air dynamics design,valves can be discharge air quickly, avoid air accumulation and formation of negative pressure. There is good sealing performance at low pressure.
3.There are BSP and NPT threads.
