The scraper I am looking at controlling currently has a Rexroth 4WE10E31/CG12N9DA on it for raising and lowering the blade.
Is there a proportional valve that is a drop in replacement for this?
Do I need a bypass so that the valve is not under constant pressure?
The tractor is old - 1997 - so nothing on board to help with this I presume.
What do I then need to connect the Arduino PWM output to the valve? Cytron? IBT2?
Thanks! Andy
