Homemade electronic hydraulics for a tractor?

Question

Arduino

I want to remake the hydraulics of an old T-25 tractor. I plan to do it on a separate control panel (xBox joystick) on some ARMe + NRF24L01. Interested in electro-hydraulic valves. If anyone has experienced this, please advise which valves are better to choose and have a low cost.

Answer 1

My work is related to the hydraulics of special equipment. Here, in essence, speaking, the electrovalve must be selected according to its throughput. And if it is clearer: the inner diameter of the inlet and outlet of the valve must not be less than the inner diameter of the inlet sleeves! Otherwise, the hoses and especially the pump will be overloaded, and the pressure relief valve will be constantly ajar in the distributor (I don’t know what distributor is in your tractor, but the pump, NS most likely) You can pick them up at dealerships for servicing excavators, loaders and other special equipment, or service shops. Imported pilots, as they are also called, in addition to their small size, what they are good for - they have built-in protection against EMF of self-induction of the coil winding (an ordinary diode in reverse polarity parallel to the coil, as in relays) I won’t say at cost, since I picked it up at the warehouse of the enterprise. And 100% will need a good adapter turner to do. I strongly do not recommend welding pipes to the valve

Answer 2

I think you made a mistake with the forum, because the choice of valves is not the topic of this resource. Look for specialized forums, and the whole thing is connected through the same relays or transistors in an elementary way.
