溢流阀在使用中有时会出现调压失灵现象。先导式溢流阀调压失灵现象有二种情况：一种是调节调压手轮建立不起压力，或压力达不到额定数值；另一种调节手轮压力不下降，甚至不断升压。出现调压失灵，除阀芯因种种原因造成径向卡紧外，还有下列一些原因：

第一是主阀体（2）阻尼器堵塞，油压传递不到主阀上腔和导阀前腔，导阀就失去对主阀压力的调节作用。因主阀上腔无油压力，弹簧力又很小，所以主阀变成了一个弹簧力很小的直动型溢流阀，在进油腔压力很低的情况下，主阀就打开溢流，系统就建立不起压力。

压力达不到额定值的原因，是调压弹簧变形或选用错误，调压弹簧压缩行程不够，阀的内泄漏过大，或导阀部分锥阀过度磨损等。

第二是阻尼器（3）堵塞，油压传递不到锥阀上，导阀就失去了支主阀压力的调节作用。阻尼器（小孔）堵塞后，在任何压力下锥阀都不会打开溢流油液，阀内始终无油液流动，主阀上下腔压力一直相等，由于主阀芯上端环形承压面积大于下端环形承压面积，所以主阀也始终关闭，不会溢流，主阀压力随负载增加而上升。当执行机构停止工作时，系统压力就会无限升高。除这些原因以外，尚需检查外控口是否堵住，锥阀安装是否良好等。

溢流阀在装配或使用中，由于O形密封圈、组合密封圈的损坏，或者安装螺钉、管接头的松动，都可能造成不应有的外泄漏。

如果锥阀或主阀芯磨损过大，或者密封面接触不良，还将造成内泄漏过大，甚至影响正常工作。

电磁溢流阀常见的故障有先导电磁阀工作失灵、主阀调压失灵和卸荷时的冲击噪声等。后者可通过调节加置的缓冲器来减少或消除。如不带缓冲器，则可在主阀溢流口加一背压阀。
