SV07B-M 是一款以计量沟槽为核心的定量阀。陶瓷转子在陶瓷定子内转动，转子沟槽舀起固定体积的液体，并从入口带到选定出口。由于液体仅接触这两个陶瓷零件，流路呈化学惰性且不含金属。
六通道阀头的沟槽容积为 6.5 微升，八通道阀头为 5.3 微升，每转一圈即重复投递该体积。驱动力 8 N/m，整机重量 0.8 kg，因此在试剂黏稠、密封偏紧或阀门在批次之间长期静置时，仍能稳定计量。
每转一圈投加多少液体？
投加量由转子沟槽决定：六通道阀头为 6.5 微升，八通道阀头为 5.3 微升。重复性来自沟槽几何尺寸，而非计时精度。
8 N/m 驱动力为何重要？
当试剂黏稠、密封偏紧或阀门长期静置时，更大的驱动力仍能带动转子。适合无人值守场合，因为一次计量卡滞就会毁掉整轮分析。
该阀可处理哪些液体？
液体仅接触氧化铝陶瓷，因此在 100 摄氏度限值内可使用强腐蚀性试剂与高纯水。请针对具体介质确认密封件兼容性。
能否脱离上位机运行？
可以。RS232 或 RS485 串口指令可直接驱动，PLC 也可通过 Modbus 控制。ASCII 与 Modbus 在同一硬件上可用。
