Rexroth Hydraulic 2

[trellend]

I had another vale go out on the beast, although I programmed it in the PLC, I know little of hydraulics.

Here is the value Part number from Rexroth: 4we6d52/ag24ndav

The diagram is here:

It controls one ram. I believe it's a 4 port, 2 position control. It has two wires coming out. Put 24 volts on there and the ram moves. I just don't understand the terminology behind this stuff, part numbers, nothing. I tried to educate myself, but this stuff is so old, it's different now.

The old one physically works if you push the pin manually, but it's resistance is now 4 ohms, when it used to be about 20-30 ohms. 24 volts, 6 amps, PLC doesn't like that at all. I need some good links on this old stuff, and somewhere to source parts. I don't care if it's Rexroth at all. It appears this is pretty standardized.

Any help out there?

Thanks,

You'll need to buy a new one. you have an old 52 series valve and the coils for those will be almost impossible to find.

See here for details...

TY. Rexroth actually called me back, and we are on the route to find the right thing. Waiting for a shop to open to call them and get an idea of when I can get this, and what else I will need. I've never changed one of these before, so I might sub that out. I don't want to dump 150 gallons of hydraulic fluid.
