Vickers SV3 10 C 3G 12DG

Hardened and ground steel construction is what sets this valve apart from lighter-duty options. That kind of material treatment means the internal components hold up under repeated pressure cycles better than soft-machined alternatives. Rated to 350 bar, which is 5000 psi, it's built for exactly the kind of demanding mobile equipment environment you're describing. Harvesters are actually one of the listed applications for this valve, so it's not a stretch to say it was spec'd with that punishment in mind.

This Vickers solenoid valve is made with a 3/8-inch port size, which should allow it to integrate into existing hydraulic systems without needing major modifications.

For function and wiring expectations, it is a 2-way, 2-position normally closed solenoid valve and it runs on 12 volts.
