溢流阀控制油路的特点通过调整弹簧的压力控制进油路的压力，进口压力恒定，p2＝0通过调整弹簧的压力控制出油口的压力，出口压力p2稳定式－通过调定调压弹簧的压力控制进油路压力；夜控式－由单油路控制压力出油口情况出油口与油箱相连出油口与减压回路相连出油口与工作回路相连泄漏形式内泄式外泄式外泄式进油口状态及压力值常态常闭（原始状态）常开（原始状态）常闭（原始状态）工作状态进出油口相通，进油口压力为调整压力进油口压力出油口压力，出油口压力稳定在调定值上进出油口相通，进油口压力允许继续升高联接方式并联串联实现顺序动作式串联作卸荷阀用时并联功用定压、溢流或安全作用限压、稳压、保压减压、稳压不控制系统的压力，只利用系统的压力变化控制油路的通断进油腔压力p1控制阀芯移动出油腔压力p2控制阀芯移动进油腔压力p1控制阀芯移动

压力控制阀 按用途分为溢流阀﹑减压阀和顺序阀。(1)溢流阀：能控制液压系统在达到调定压力时保持恒定状态。用於过载保护的溢流阀称为安全阀。当系统发生故障，压力升高到可能造成破坏的限定值时，阀口会打开而溢流，以系统的安全。(2)减压阀：能控制分支回路得到比主回路油压低的稳定压力。减压阀按它所控制的压力功能不同，又可分为定值减压阀(输出压力为恒定值)﹑定差减压阀(输入与输出压力差为定值)和定比减压阀(输入与输出压力间保持一定的比例)。(3)顺序阀：能使一个执行元件(如液压缸﹑液压马达等)动作以后，再按顺序使其他执行元件动作。油泵产生的压力先推动液压缸1运动，同时通过顺序阀的进油口作用在面积A 上，当液压缸1运动完全成后，压力升高，作用在面积A 的向上推力大於弹簧的调定值后，阀芯上升使进油口与出油口相通，使液压缸2运动。 
流量控制阀 利用调节阀芯和阀体间的节流口面积和它所产生的局部阻力对流量进行调节，从而控制执行元件的运动速度。流量控制阀按用途分为 5种。(1)节流阀：在调定节流口面积后，能使载荷压力变化不大和运动均匀性要求不高的执行元件的运动速度基本上保持稳定。(2)调速阀：在载荷压力变化时能保持节流阀的进出口压差为定值。这样，在节流口面积调定以后，不论载荷压力如何变化，调速阀都能保持通过节流阀的流量不变，从而使执行元件的运动速度稳定。(3)分流阀：不论载荷大小，能使同一油源的两个执行元件得到相等流量的为等量分流阀或同步阀；得到按比例分配流量的为比例分流阀。(4)集流阀：作用与分流阀相反，使流入集流阀的流量按比例分配。(5)分流集流阀：兼具分流阀和集流阀两种功能。
