迪普马DUPLOMATIC先导式溢流阀RQ4M6-SAT/51
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：
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。
