其特点是液压泵的出口压力仅仅比负载开一个节流阀阀口的压差，也就是高一个定差溢流阀所确定的压差。
也就是说随着负载压力的升高，系统压力有可能高出允许值，为此，就增加一个先导阀RY。
这个先导阀一般是手调式。
这样一来，当系统压力达到先导阀调定值时，先导阀与主阀合成，其功能由定差溢流阀转变成常规溢流阀，限制了系统最压力。

如果阀中的节流阀用比例节流阀，先导阀用比例压力阀，则构成电液比例压力流量复合控制阀，俗称PQ阀（也称双比例），塑机行业用的不少。
PQ阀具有压力流量复合控制功能，但干起活来还是分开来处理的，就是说，当控制压力时，流量阀让一让（将流量输入值调大，以不影响压力的控制）；当调节流量时，压力阀让一让（将压力输入值调高，以不影响流量控制）。
随便提到，由三通调速阀引申出来的阀还不少，例如工程机械用的单路稳流阀，优先阀等等
