TECH SPECSAccessoriesAir Vents, Software, Pressure Regulators, Pressure Gauges and ToolsAir VentsSuperior protection againstair blockage and vacuumcollapse. Great value.The RB-2AV Air Vent / Vacuum ReliefValve has a large orifice to allow air toescape during pipeline filling and toreenter during pipeline draining. Duringpipeline filling, air must be allowed toescape to prevent blockages and surges,which can damage the pipe. And duringpipeline draining, air must be allowed toreenter to prevent vacuum, which cancause the pipe to collapse. These valves donot release air from pipelines once thepipelines are under pressure.The RB-2AV valves are typically installedat all high points along the line, near allpipe ends, downstream of any line shutoffvalve, upstream of pump check valves,and every quarter of a mile on longpipelines.Rain Bird Air Vent / Vacuum Relief valvesare manufactured of cast aluminum(body), engineering grade plastic (float),and 300 series stainless steel (stem).RB-2AV valves are the ideal choice forall irrigation systems.• Patented, aerodynamic float design• Lightweight• Pop-up stem indicator• Economical• 2 in NPT/ 50 mm inlet• 1.75 in / 44,5 mm orifice• Pressure Range: 2-150 psi / 0,1-10,3 barsAir VentsHow to Order:Product LineIdentificationRB - 2 - AVInlet SizeLiquid-Filled Pressure GaugesHow to Order:RBG - L - 30 - DCProduct LineIdentificationLiquid-FilledDisplay CaseGauge Scale(U.S. and Metric Units)Liquid-Filled PressureGaugesAccurate, durable, andeconomical.RBG liquid-filled pressure gauges areaccurate, durable, and economical. Theyare built to operate with irrigation andother agricultural systems and machines.The stainless steel case and glass lens areheavy duty and weather and chemicalresistant. The glycerine fill is nonyellowing,prevents fogging, and dampensvibrations, pulsations, and surges.The RBG-L has a 2 1/2 in / 65 cm dial faceand 1/4 in NPT connector.• Glycerine-filled for long life• High accuracy• Rugged stainless steel case• Glass lens• Large numbers for easy reading• Dual display (psi / bars)• Easy to operate pressure release valvefor greater accuracyModel Gauge QuantityNumber Scale perpsi bars CartonRBG-L30DC 0-30 0-2 15RBG-L60DC 0-60 0-4 15RBG-L100DC 0-100 0-7 15RBG-L160DC 0-120 0-11 151 bar = approx. 100kPa
