Spirax Sarco exhaust valveSteam system with automatic exhaust valve Air and other non-condensable gases in the steam system will cause a lot of problems . Warm-up time will be extended only , and the mixture of steam and air at the same pressure will be lower than that of pure steam temperature . Air film reduces heat transfer efficiency , resulting in increased fuel consumption , and these gases are also the main reason for the air pipe corrosion formation . Use automatic exhaust valve Spirax Sarco steam system to exclude air and other non-condensable gases , while not leaking steam. AV13 - using brass body , threaded connections, the working pressure 13barg, corrosion-resistant and built-in filter . AVC32 and AVS32 steel and stainless steel were used . Threaded , flanged and welding connections , corrosion and built-in filter . Water supply pipeline with automatic air eliminator Air and other non-condensable gas inside the water pipe will cause a lot of problems , such as noise , corrosion, hysteresis loop , and even cause a temporary interruption of the device. When these gases are introduced into the water filling pipe , thorough and effective way to effectively eliminate the use of these gases automatic air eliminator . Spirax Sarco air eliminator use the float buoyancy action. Air exclusion is a natural gathering place installed in the air exclusion can automatically turn on to exclude air and automatically shut down when the water passes through . Air exclusion is automatic work , either in the boot or runtime are no adjustment .Air vent for the following applications :    Automatically exclude air    S emptying liquid systems    Steam system to exclude airAvoid residual air system , or waste steam 斯派莎克AV13排空气阀蒸汽系统用自动排气阀 空气及其它不凝性气体在蒸汽系统中会引起很多问题。不但会延长暖机时间，而且在相同压力下蒸汽及空气混合物会比纯蒸汽温度低。空气会形成气膜降低传热效率，从而导致燃料耗量增加，并且这些气体也是管道腐蚀的主要原因。使用斯派莎克的自动排气阀可排除蒸汽系统中的空气及其它不凝性气体，同时不会泄漏蒸汽。 斯派莎克AV13排空气阀 - 采用黄铜制阀体，螺纹连接，工作压力13barg，耐腐蚀并内置过滤器。 AVC32和AVS32分别采用钢结构和不锈钢结构。螺纹，法兰和焊接等连接方式，耐腐蚀并内置过滤器。 斯派莎克排空气阀AV13给水管道用自动空气排除器 给水管道内的空气及其它不凝性气体会引起很多问题，如噪音、腐蚀、循环迟滞，甚至造成设备的暂时中断。这些气体是在管道充水时引入的，彻底而有效地排除这些气体的有效方法是使用自动空气排除器。 斯派莎克AV13排空气阀利用浮球的浮力动作。空气排除器安装在空气自然聚集处，排除器能够自动开启以排除空气，并在水通过时自动关闭。空气排除器是自动工作，无论在开机或运行时均无需调节。
