    when spool is in null postion, should we get oil in A and B, we have tested on Directional valve, we inserted 150 barg on P and we are gettingoil drop on Port A and B, is this normal in Null Postion without any command to Solonoide valve

    Interesting. It is like trying to pull out the plunger of a syringe while your thumb is covering the air hole. Except the seal would be at the top, not against the cylinder walls. So for creep to occur, more oil must be able to get pulled into the cylinder.

    We are facing one critical issue with on board proportional card rexroth +/- 0 to 10 V. With -ve voltage apply some time valve start working in +ve supply direction so operation got opposite. After reset valve supply same valve start to work normal. Sir, Please suggest root cause and solution.......
