kracht溢流閥SPVF 40 A1 G1 A12構(gòu)造：
滑動活塞2在壓縮彈簧3作用下壓在環(huán)形區(qū)域a上。因此與泵想通的P口同與油箱相通的R口被直徑d處的密封隔離開。一旦工作壓力達(dá)到由調(diào)節(jié)螺釘4調(diào)定的壓力，滑動活塞2開始卸荷液壓油至油箱。彈簧腔b由孔c進(jìn)行壓力補償。開始時，彈簧腔b一定要通過放氣孔5（六角螺釘）進(jìn)行排氣。
kracht溢流閥SPVF 40 A1 G1 A12構(gòu)造
閥盡量垂直安裝，使壓力調(diào)定量垂直向下。
該溢流閥有4種壓力調(diào)節(jié)范圍，這是因為彈簧的壓縮比決定了每種彈簧只能覆蓋有限的壓力調(diào)節(jié)范圍。
