在插装阀的控制口配上不同的先导压力阀，便可得到各种不同类型的压力控制阀。图8(a)所示为用直动式溢流阀作为先导阀来控制主阀用做溢流阀的原理图。A腔压力油经阻尼小孔进入控制腔和先导阀，并将B口与油箱相通。这样锥阀的开启压力可由先导阀来调节，其原理与先导式溢流阀相同。如果在图8(a)中，当B腔不接油箱而接负载时，即为顺序阀。在图8(b)中，若二位二通电磁换向阀通电，则作为卸荷阀用。减压阀原理图，主阀芯采用常开的滑阀式阀芯，B为进油口，A为出油口。A腔压力经阻尼小孔后通控制腔和先导阀，其工作原理和普通先导图(见图8)压力控制插装阀式减压阀相同。

在插装阀的控制盖板上增加阀芯行程调节器，以调节阀芯开度，则锥闻可起流量控制阀的作用。若在二通插装节流阀前串联一个定差减压阀，就可组成二通插装调速阀。若用比例电磁铁取代节流阀的手调装置，则可组成二通插装电液比例节流阀。插装阀产品介绍：国内生产的产品有TJ系列、Z系列、力士乐系列等，这些产品除结构上有所区别外，压力等级均是31.5MPa，通径范围Фl6～Ф160mm。
