VICKERS-1CEL90F30S230/60

It's designed for use in heavy-duty equipment like harvesters and refuse haulers, so it should be a good fit for your harvester. It's also used in various mobile and industrial applications, so it's a versatile valve.

Refuse haulers are actually one of the named applications for this valve, so it's built with exactly that kind of duty in mind. The pilot-assisted relief with check style gives you stable control when loads are moving or shifting, which is where a lot of valves fall short on that type of equipment. It's rated to 350 bar (5000 psi) and handles up to 90 liters per minute on flow, with a peak capacity of 550 L/min (143 USgpm). That combination handles the pressure swings and flow demands you'd expect in refuse hauler cycles without losing stability.
