VICKERS RV8-8-S-0-15/2.5-00

A poppet valve like this RV8-8 uses a cone-shaped plug to control flow. That design helps it seal reliably and respond quickly to pressure changes, which is why they're good for mobile equipment and industrial uses.

Harvesters are actually one of the listed applications for this valve, so you're in the right place. It's a poppet-style pressure control valve built to handle up to 350 bar (5000 psi), which gives it plenty of headroom for the demands that come with agricultural harvesting equipment. The flow rate on this unit is 30 liters per minute, so as long as that lines up with your system's requirements, it should drop right into that application without issue.
