BTSV-SB系列线内闭环采样阀系统，设计用于高效收集有毒危险流体介质生产处理过程中有代表性的样品。无密闭空间结构的阀门，既可以安装在水平管线，也可以安装在垂直管线，因此可以让流体介质常态流经阀门，并环绕锥形轴流动。采样瓶既可以开启顶部，也可以采用隔膜密封，直接安装在阀门下，方便采样流程。

The BTSV-SB series in-line closed-loop sample valve system is engineered to effectively collect representative sample of hazardous process media. The dead space free design can be installed in both horizontal and vertical piping thus allowing the media to constantly flow through the valve and around the conical spindle. Sample bottles either open top or sealed with septums can be directly attached beneath the valve to facilitate the sampling process.
