Garden Hose Connection Accessories Automatic Air Vent Valve with 1", 3/4" Male Screw Garden Exhaust Valve Intake and Exhaust Valves Plumbing Fittings 10 Pcs (Color : Black, Diameter : 3/4'')

Tight connection: the connection is tight and not easy to fall, ensuring complete prevention of leakageSpecification: Item name: Air Vent Valve Entrance size: 3/4 Inch, 1 InchConnection form: BSPT external thread Packaging: 10 PcsTechnical parameter: Pressure rating: PN10 Operating pressure range: 0.1-10Bar Operating temperature: the water temperature is 50 degrees centigrade Size: 125 X 40mm/4.92 X 1.57inch. (height x outside diameter) Product description: 1.The vacuum intake and exhaust valve is a power type quick intake and exhaust valve, suitable for various irrigation system. When the system is water injected, the air valve discharges a large amount of air in the pipeline. When the system is emptying, the air valve attracts a large amount of air to prevent the vacuum negative pressure. 2.The valve adopts advanced compound gas dynamics design, with fast intake and exhaust, can avoid air accumulation, prevent formation of negative pressure, has good sealing performance if it is low pressure. Features and advantages: Small size, simple structure and reliable performance. The valve body adopts the direct passage design, the inlet and outlet are large in size and large in flow. Sealed float moves long length, Prevents floating balls from blowing high velocity air, resulting in premature exhaust closure, and does not affect air inhalation or removal. Dynamic low pressure seal. It can maintain good tightness at low pressure (0.3bar) and avoid leakage. All components have advantages of corrosion resistance, low maintenance frequency and long service life. Working principle: In the process of water injection, a large amount of air is rapidly discharged from the intake and exhaust ports; After the water enters the air valve chamber, the float rises with the liquid level and closes the quick intake and exhaust port. Valve design in accordance w
