Electro hydraulic valve control

[Gettin by]

Refurbishing hydraulics and control system on sprayer boom controls.
Vickers valves which can stay but hoping to replace the electrics.
attached are valve decals and the control box.
Two questions for the collective wisdom.
Firstly, what is this valve definition and secondly can I bypass the junction box and use pg 11 connectors on the valves with or without LED or rectifiers?
The ideal would be a simple small button box in the cab and wiring directly to the spool solenoids. Any opinions appreciated. Thanks.

Have you got any relays on the other side of the board...do you need the system or can you plumb staight into tractor...

Can tell you you have a 3/2 valve. 3 positions with 2 ports.

Thanks.
3 slices above that slice. One for inner boom fold, one for outer boom fold and one for tilting or yaw.
I think that last slice above was a centralising cylinder to level out the booms for folding.
in answer to the other question there aren’t any other relays on the board. Control box toggle switches are direct to the junction box pictured and then solenoid connectors are just the plugs with spade connectors inside. Hoping to simplify while maintaining improving along with new booms and other goodies!
Thanks.

Not the best picture but they just look like Cetop valves,I’ve them on similar without anything fancy just switches.

Bigger possibly better photo of the valve block.

The box looks fairly tidy to be honest. Plus it has diodes fitted for some protection.
There is no reason u couldn’t make your box and wire to the solenoids, but you need to prevent spikes back to your tractor electrics. The PG11 u mention refers to the threads on the cable gland. The connectors onto the solenoid are referred to as din connectors. Possibly din 43650. Led ones are very handy for fault finding, and some of these connectors include the diode which would be in your current box, to prevent spikes.

Thanks. Probably install a new box with the existing board and keep the system simple.
