Basic Info.Model NO./TypeCompound Exhaust ValveMaterialNylonCertificationISO9001Trademarkxuanyuan/OEMTransport PackageCartonSpecification1"BSP/NPTOriginTaizhouHS Code3917400000Product DescriptionFEATURE & ADVANTAGE• Advanced aerodynamic design;• Big inlet size allowing massive air flow;• One- piece floating ball design ensure ontime shutting of outlet while the high speed airflow occurs;• Quality sealing - prevents leakage under low pressure conditions (0.1 bar/1.5 psi);• PP material with corrosion, acid, alkliane resistant features to be long lasting;• Multi-installation size for various market demands.HOW IT WORKSSystem filling - During filling water into the pipeline, massie air will be evacuate from kinetic air intake & exhaust hole. Thefloating ball moves upwards to close the orifice after water flows into the champer. With aerodynamic design and the anti-blow design, the floating ball ensure ontime shutting of outlet while the high speed airflow occurs.Pressurized Operation - The kinetic valves keeps closed under pressure from water.System draining - When the system or pipe is drained empty, negative pressure forms in the kinetic valve. Meanwhile the float move down to take in air against vacuum formation.Zip Code:318058Address:No.239,Zhenqian East Road,Juanqiao Village,Jinqing Town,Luqiao District,Taizhou City,Zhejiang Province,China  Taizhou Xuanyuan Irrigation Equipment Co.,Ltd. engages in  irrigation system.Our products covers almost all the water-saving irrigation areas.Including:farmland sprinkler and drip irrigation,greenhouse micro spray and drip irrigation,road greening engineering maitenance irrigation,cooling and disinfection for livestock breeding and special cultivation temperature sid infection ,etc.
