4、电源条件
1）根据供电电源种类，分别选用交流和直流电磁阀。一般来说交流电源取用方便；
2）电压规格用尽量优先选用AC220V.DC24V；
3）电源电压波动通常交流选用+%10%.-15%，直流允许±%10左右，如若超差，须采取稳压措施；
4）应根据电源容量选择额定电流和消耗功率。须注意交流起动时VA值较高，在容量不足时应优先选用间接导式电磁阀。

节流阀是通过改变节流截面或节流长度以控制流体流量的阀门。将节流阀和单向阀并联则可组合成单向节流阀。节流阀和单向节流阀是简易的流量控制阀，在定量泵液压系统中，节流阀和溢流阀配合，可组成三种节流调速系统，即进油路节流调速系统、回油路节流调速系统和旁路节流调速系统。节流阀没有流量负反馈功能，不能补偿由负载变化所造成的速度不稳定，一般仅用于负载变化不大或对速度稳定性要求不高的场合。

减压阀的作用原理是靠阀内流道对水流的局部阻力降低水压，水压降的范围由连接阀瓣的薄膜或活塞两侧的进出口水压差自动调节。定比减压原理是利用阀体中浮动活塞的水压比控制，进出口端减压比与进出口侧活塞面积比成反比。这种减压阀工作平稳无振动；阀体内无弹簧，故无弹簧锈蚀、金属疲劳失效之虑；密封性能良好不渗漏，因而既减动压（水流动时）又减静压（流量为0时）；特别是在减压的同时不影响水流量。
