SmartSV04M-B 是一款多通道切换阀，用于在 1 个公共端口与最多 28 个其他端口之间切换液路。陶瓷转子在陶瓷定子内转动，通过转子沟槽将中心端口与选定出口连通。液体仅接触这两个陶瓷零件，因此流路呈化学惰性且不含金属。
共 7 种阀头，覆盖 6 至 28 通道，流道直径 1.2 mm 至 0.6 mm。端口间容积从最宽流道的 27.5 微升至最窄的 7.8 微升，决定每次切换的残留携带量。阀头可承受 100 摄氏度液体，整圈切换耗时 4 秒。
有多少种通道数可选？
阀头提供 6、8、10、12、16、24、28 通道版本。通道数越多流道越窄，从 1.2 mm 收窄至 0.6 mm。
什么决定样品间的残留携带？
端口间容积：1.2 mm 流道为 27.5 微升，0.6 mm 流道降至 7.8 微升。流道越窄残留越少，但流量也受限。
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。
