    Default Rexroth solenoid operated valve ID

    I just purchased a 3 valve manifold with solenoids for a project and I would like to decode the part number. As there is a 12 in there I am hoping it is 12 volts. There are 2 wires on each side of each valve. The thing that puzzles me is that if I blow into the P port while blocking the T port I get flow from cylinder ports. Is this normal when no pressure and no electricity is applied? Google is not helping me to find valve specs, the number is 4we6h52/ag12nda s043a-488 rexroth
    Any body familiar with these things?

    You may be able to cross reference it with an asco valve.

    Rexroth hydraulics is in fact Bosch, aka Robert Bosch, thier usual m.o. is to run at 24v, the mount being 3 flat plate terminals at the solenoid cap.
    I’m sure they do 12. But that would bo the mobile kit for excavators cranes
    Etc,
    I don’t know how your block is connected but it’s going to be ceetop standard or EU standard, you could be looking at a different block as there was a screw in plug supposed to be in there making it a 4/5 to 2 spool animal

    They do appear to be called cetop valves, who would know how the part number is coded?
