1）根据使用的工作介质选SMC流体阀的系列
2）根据几位几通的要求、阀的零位状态，电磁阀还是气控阀的要求，直动式还是先导式的要求和接管口径的要求等，选择阀的系列
3）确认流体阀使用的工作介质是否为适合流体。要查明阀体材质、密封件材质、线圈绝缘等级、静铁心及阀芯的支持座等的材料都能适应该流体，使用可燃性油和可燃性气体时，要注意阀的泄漏量是否符合要求。
4）确认动作压力差。
5）检查流量是否满足要求
1）必须确认使用的工作介质是否适合所选定的流体阀。应检查该阀的阀体材质、阀座材质、密封件材质、线圈绝缘等级、电源种类、使用温度范围等都应满足该工作介质的要求。
2）不要在有腐蚀性和爆炸性气体的场合使用。使用可燃性液体或气体时，内外泄漏量应符合规格要求。
3）流路中不允许有油之类的污染物时，应使用禁油规格。
4）工作介质为液体时，其粘度一般在50×10^-6m^2/s以下。液体中不得混入异物。
*高动作压力差：指在阀开启或关闭状态，动作时能允许的高压力差，即一次侧与二次侧压力之差。当二次侧压力为大气压时，就变成高使用压力。
*低动作压力差：指主阀芯保持全开状态所需的低的压力差（即一次侧与二次侧压力之差）。
*禁油处理：表示与流体接触的阀内的零部件经脱脂洗净处理。
*孔口直径：指控制流量的小孔直径。通常是指阀座上的开孔直径。
