Danfoss / Eaton Integrated Hydraulics 1SEL140F20S1

Load drift on a lift circuit is exactly the kind of thing this valve is built to address. The pilot-assisted relief with check design gives you active resistance against unintended movement under load, which keeps things stable when the operator isn't actively commanding motion. It's rated for flows up to 140 liters per minute in this configuration, and it carries ISO8643 compliance, which is the relevant standard for load-holding performance in mobile equipment. Harvesters are actually one of the listed application types for this valve, so you're in the right place.
