VALVE MODEL # 4WRPEH 6 C3 B04P-20/G24K0/A1M VALVE MODEL #
http://www.boschrexroth.com/country..._servo_valves/a_downloads/re29035_2009-02.pdf
I am atttempting to control teh speed of a hydraulic motor by replaceing a valve (DG4V-3S-20-M-FW-B5-60)
with the proportional valve indicated above.
However, my valve doesn't ever seem to shift.I am suppling +24vdc to pin A and common to pin B.
Also have a +- 10 v signal on Pins D and E from a 1771 ofe analog output card. I have all my voltages at the valve connector but never receive any change from the valve.
The valve has onboard electronics so I have not installed any amplifier.
Am I missing something obvious?
Does Pin C require a reference to ground?
I'd appreciate any feedback.
