4WEH32G50/6AG24NZ5L    电液换向阀    上海液二生产的
想加一个叠加式双单向节流阀    不知道用什么型号好
有没有懂的回个帖呢

没有见过这么大通径的叠加阀。这么大的流量用节流阀调速不节能不环保啊，现在哥本哈根开会正在抓这个问题，你用了这么大的节流阀可能导致地球温度上升0.00000000000000000000000000000000000000000000000000000162度。

电液阀是这样用的:

In order to influence the switching time of the main valve (1) a double
throttle check valve (2) (type Z2FS 6 to catalogue sheet RE 27 506)
has to be fitted.
Conversion from meter-in (3) to meter-out control (4):
Remove the pilot valve (5) leave the seal ring support plate (6) in
place, rotate the throttle valve (2) about its longitudinal axis and
refit it, replace the pilot valve (5).

用电液阀,就是为了实现快速。再搞个节流阀，就多此一举了。
