伺服阀的主阀是靠前置级阀的输出压力来控制的。而前置级阀的压力则来自于伺服阀的入口p,假如p口的压力不足,前置级阀就不能输出足够的压力来推动主阀芯动作。而我们知道,当负载为零的时候,如果四通滑阀打开,p口压力=t口压力+阀口压力损失(忽略油路上的其它压力损失。
它比手动先导阀具有更多灵活性和更高控制精度,可以制成比例伺服控制手动多路阀,不同输入信号,REXROTH减压阀使输出活塞具有不同压力或流量进而实现对多路阀阀芯位移进行比例控制,四通或多通螺旋插装式比例阀可以对工作装置实现单独控制。

1、介质特性
1)质气,液态或混合状态分别选用不同品种的电磁阀;
2)介质温度不同规格产品,否则线圈会烧掉,密封件老化,严重影响寿命命;
3)介质粘度,通常在50cSt以下。若超过此值,通径大于15mm时,用多功能电磁阀;通径小于15mm时,用高粘度电磁阀。
4)介质清洁度不高时都应在电磁阀前配装反冲过滤阀,压力低时,可选用直动膜片式电磁阀;
5)介质若是定向流通,且不允许倒流,需用双
